The Vermont State Police are assisting federal authorities after a shooting involving a Border Patrol agent. They said it happened around 3:15 p.m. Monday on Interstate 91. The FBI is leading the investigation.

The shooting on Monday in Vermont near the Canadian border followed the surveillance of an armed couple who dressed in black tactical-style clothing.

A woman has been arrested in connection with the fatal shooting of US Border Patrol agent earlier this week on a highway in Vermont close to the US-Canadian border, the FBI office in Albany said Friday.
