Harvard University briefly implemented a shelter-in-place order Friday morning while police searched for a suspect on a bicycle who allegedly shot at another person in Cambridge.

“Cambridge Police are currently on-scene of a shots fired incident that took place on Sherman Street in the vicinity of Danehy Park,” a spokesman for Cambridge police told Boston.com via email. “Ballistic evidence has been recovered.”

There aren’t any known victims or concerns about public safety risk at this time, the spokesman confirmed.

Harvard issued multiple emergency alerts to the community before noon, warning that university and Cambridge police were searching for the suspect near the Radcliffe Quad.

By noon, the university had lifted the shelter in place.

“Please continue to be vigilant and report any suspicious activity to the HUPD at 617-495-1212,” a Harvard alert noted.

This is a developing story, which will be updated as more information becomes available. Harvard updates emergency situations on campus on its emergency alerts page.

A man accused of abusing a dog in Boston’s Dorchester neighborhood over the summer has a history of mental health and other health issues, his attorney said.

Akeem Pierre was arraigned Thursday in Dorchester District Court on animal cruelty charges, where he pleaded not guilty.

Video allegedly shows dog being abused

Back in June, Assistant District Attorney Nadia Eldemery said Pierre was seen walking a dog named Pluto in Dorchester. A witness told police they saw Pierre whip Pluto with the leash several times on the face and body, along with yelling at the dog and threatening him. The witness, who filmed the incident, also said Pierre lifted Pluto up off the ground by the leash and tugged him down the street. The dog allegedly seemed hesitant to walk with Pierre and appeared anxious.

Eldemery said the witness filmed the incident and sent the video to the MSPCA and police. The video was also posted on social media.

When police spoke with Pierre, he told them he was pet-sitting Pluto and “training” him by tapping him on the nose whenever he did something deemed inappropriate. Police said Pierre did not dispute or deny what he did in the video and did not show any remorse.

Suspect has mental health issues, attorney says

Pierre’s defense, attorney Elizabeth Pardy, said he has a long history of medical and mental health issues, which is why he was also in default on an OUI case from 2021. She said he’s bipolar, schizophrenic and has sickle cell anemia, along with other issues. She said he underwent a competency evaluation and the doctor determined that he’s not competent to stand trial.

Judge Thomas Kaplanes released Pierre on his own recognizance, despite the prosecution requesting $2,000 bail. He was ordered to have no interaction with Pluto, surrender any animals in his custody, report to probation weekly and remain drug and alcohol free. The judge also ordered him to undergo a mental health evaluation.

Pluto was taken to a veterinarian and was found to have no injuries. He was then brought to the MSPCA, who confirmed that he’s been adopted and is doing well.

“We’re grateful to the public for bringing this to our attention, which allowed our officers to quickly start a swift investigation that brought Pluto safely into our care and also secured charges, which are now pending before the courts,” said the MSPCA in a statement. 

The Celtics showed flashes of what they can be at their best this season, but the 76ers got a historic rookie performance from VJ Edgecombe and a huge game from Tyrese Maxey to take the season opener. 

Here are the takeaways. 

VJ Edgecombe and Tyrese Maxey both looked incredible

Rookie wing VJ Edgecombe looked more than worth the Sixers’ robust tanking efforts last season in his regular-season debut. Edgecombe broke the NBA record for most points in the first quarter by a rookie with 14, surpassing LeBron James’ record of 12, and he broke the Sixers’ record for points in a rookie debut of 30 set by Allen Iverson, pouring in 34 on 13-for-26 shooting, including several earth-shaking dunks.

“For a rookie to come in, first game and put up (those numbers), it was impressive,” Derrick White said. “I don’t know if I’ve ever seen somebody have that in his debut, but he had a really good game.”

Point guard Tyrese Maxey, meanwhile, looked every bit up to the task of being the Sixers’ primary superstar this season, pushing the Sixers out to a halftime lead and pulling them back from the brink when Boston threatened to pull away in the fourth. Maxey finished with a massive 40-point outing, running rampant through a Celtics’ defense that struggled to get back and defend him whenever they missed shots. 

The Sixers are far from a perfect roster, but tanking last season appears to have worked wonders for them, and as The Process Pt. 1 appears to be coming to a close (more on that in a minute), they appear very well set up to begin The Process Pt. 2. 

The final play(s) were supposed to be for Jaylen Brown

After letting a double-digit lead slip away, the Celtics looked like they were done, but Edgecombe missed two late free throws that gifted them a final chance.

With eight seconds left, Derrick White struggled to inbound the ball before finally dishing to Payton Pritchard. Pritchard drove into the paint and had his shot blocked out of bounds with just over a second remaining.

On their last, last chance, the Celtics once again passed to Pritchard, who created a little space but missed the potential game-winner.

According to Pritchard, the play was designed for Jaylen Brown.

“They kind of shadowed it,” Pritchard said. “I got it, attacked, probably just made the wrong read. Anfernee (Simons and Sam (Hauser) were open on the back side, so that’s just a pass I’ve got to make.”

For his part, Mazzulla said the goal was to get the ball to the Celtics’ ball-handlers.

“We got the ball into the paint, got a decent look,” Mazzulla said. “It’s all you can do is get it to those guys, and they gave us a chance to win.”

The Celtics might regret letting that one slip

At the risk of sounding overly reductive, the Celtics really need to get wins this season when the opportunities presents themselves, and Wednesday’s game was a prime example. 

On a night when the player best suited to hurt them looked like a shell of himself, and when they built a double-digit second-half lead against a shaky roster propped up by two superhuman performances, the Celtics couldn’t claim their first win of the season. 

That puts them in a precarious position over their first seven games. Their next contest is on the road against the Knicks, who are widely considered a genuine championship contender this season. That’s the start of a three-games-in-four-night stretch, during which their most beatable opponent (the Pelicans) is the opponent they face last. They then take on the Cavaliers (another championship contender), this 76ers team again, and the Rockets (yet another championship contender, who looked like a heavyweight in their showdown against the Thunder on Tuesday). 

When the dust settles, the Celtics could be in a tough position in the standings, and while it’s still clearly very early in the season, this is not last year’s roster – digging out of an early hole will be much more difficult. 

The Jaylen Brown/Derrick White tandem debuted well

Brown and White scored 25 points apiece in their debut as the new Celtics stars. Brown dished out four assists early and shot 9-for-18 from the floor, and he played the kind of patient floor game the Celtics need from him in the absence of Jayson Tatum. 

Prior to the game, Brown was questionable with a hamstring injury suffered during preseason.

“It was fine. I thought it held up well,” Brown said. “Definitely got to do some recovery. Within the first two weeks coming back from a strain, you’ve got to make sure that you get your recovery in because that’s when the risk is at its highest.

So I’ve just got to make sure I’m focusing on my body, getting my rest, doing my recovery, and getting ready for the next game.”

White, meanwhile, went ice-cold with the rest of his teammates from three in the second quarter – at one point, the Celtics missed nine straight – but he came alive in the third, and he worked his way to the line seven times. 

Anfernee Simons looked like a nice addition

The Celtics reportedly spent the summer checking on what they could get for Simons on the trade market, and that option is still likely on the table – this is, after all, a team very much in flux – but the early returns are promising.

Simons was as advertised offensively. He hit multiple 3-pointers that barely disturbed the net on their way through, he attacked the basket in late-shot-clock situations and created offense out of nothing, and at one point in the fourth quarter, he exploded to the rim and elevated so quickly off the ground that Tyrese Maxey could only jump out of his way futilely as Simons thundered home a two-handed slam.
