Vermont, Mont.

— The Transportation Security Administration has confirmed that an agent who was killed on Saturday at a Vermont train station is an employee of the agency and that his death was a result of being shot during a struggle with another agent.

The Associated Press reports that an agency spokeswoman said Friday that the agent was one of four people shot at the station by another TSA agent who said he had to shoot because he didn’t have time to reload his weapon.

The agency did not provide further details.

Vermont Police Chief Mark Bier said the shooting happened just before 2:30 p.m. at the train station near the airport.

He said that during the confrontation, an unidentified man tried to force his way into the station, and a second TSA agent fired several shots at the man.

Bier declined to say what those shots were.

“This is a sad day for the entire Vermont community, and we will do everything we can to ensure a smooth and safe operation for the next day,” Vermont Mayor John Bostock said in a statement.
