A United Airlines flight bound for Minneapolis from Chicago was reportedly diverted after an “unruly passenger” tried to breach the cockpit late on Friday.

The FBI and police responded to reports of a security concern with the passenger, who was detained by police at the Dane county regional airport in Madison, Wisconsin.

The flight continued its journey to Minneapolis, landing early on Saturday morning, according to FlightAware data. There were no reported injuries among the 147 passengers and six crew members onboard the flight.

A United spokesperson said flight 2005 “landed safely in Madison … to address a security concern with an unruly passenger”.

The FBI in Milwaukee said the agency was notified of the flight’s diversion, and its agents, along with local law enforcement, responded to the airport.

“A subject was detained by the [local] sheriff’s office, and afterwards passengers resumed their flight,” an FBI spokesperson said.

In air traffic communications reported by NBC News, personnel onboard the plane could be heard discussing the attempted cockpit breach with ground control.

“I do not believe they ever cuffed him, but they were able to finally get control of him after multiple attempts to try to breach the cockpit,” a member of the crew said. “I believe at this point he is seated in a seat and flanked with law enforcement officers on either side.”

Aircraft hijackings are almost unheard of in the US since the September 11 terrorist attacks in 2001, when four aircraft were taken over by Islamic extremists, including two that crashed into and destroyed New York’s World Trade Center.

But between 1968 and 1972, known as hijacking’s so-called golden age, more than 130 US planes were hijacked. Many of those hijackers demanded to be flown to Cuba.

An ICE agent facing several assault charges in connection with a January shooting involving two Venezuelan people in Minnesota has been arrested in Texas, the Hennepin County Attorney’s Office said.

Christian Castro was charged earlier this month with four counts of second-degree assault and one count of falsely reporting a crime.

CNN is working to determine whether Castro has an attorney and has reached out to the Department of Homeland Security for comment.

Castro faces those charges in connection with the shooting of Julio Sosa-Celis, a Venezuelan man shot in the leg through the front door of a Minneapolis home. The incident took place during the Trump administration’s immigration enforcement blitz in the Twin Cities.

Originally, Sosa-Celis and his cousin Alfredo A. Aljorna were facing federal charges after DHS said they had attacked an agent, prompting him to fire a defensive shot.

But the Justice Department dropped the charges in February, and Immigration and Customs Enforcement said two of its agents, who made false statements about the incident under oath, were placed on administrative leave.
