Boston police arrested four people on Friday in shoplifting incidents at Lululemon and Alo stores in the city.

Officers were told just before 4 p.m. that two female suspects had stolen merchandise from the Alo store at 776 Boylston Street and were then stealing from inside of the Lululemon store. Police say they were able to stop the suspects as they were exiting the store, and a further investigation showed that one suspect had stolen merchandise from both locations, totaling approximately $516.

A 15-year-old girl was arrested and is expected to be arraigned in Boston Municipal Court for two counts of shoplifting by asportation, police said.

Then, at about 5:15 p.m., officers were again contacted and told that there were two known shoplifters inside of the store. The suspects, who were allegedly seen concealing multiple items into their jackets, pants and bag, were also stopped as they exited the store, and police recovered approximately $1,422 in stolen merchandise.

Both 31-year-old suspects — identified as Kayla Harris, of Boston, and Demetrius Little, of Roxbury — are charged with larceny over $1,200 and conspiracy. They’re also expected to be arraigned in Boston Municipal Court.

A short time later, at about 6 p.m., officers were told that a group of individuals were attempting to conceal items. Police were able to stop the group as they headed in the direction of Huntington Avenue. One suspect immediately attempted to get away, according to police, but the suspect was quickly stopped, leading to a struggle.

The suspect allegedly actively resisted officers, who continued to give verbal commands to stop resisting. The suspect — a 14-year-old boy — was placed into handcuffs, and approximately $296 in stolen merchandise was recovered, police said. He’s expected to be arraigned in Boston Juvenile Court for shoplifting by concealing merchandise and resisting arrest.

Attorney information wasn’t immediately available for anyone arrested, and Boston police say it’s too early in their investigation to determine if these incidents are connected to other notable shoplifting occurrences that have occurred at these stores in recent weeks.
