The FBI lost two guns in Andover yesterday and it wants the public’s help to find them.

“The Boston Division of the FBI is offering a reward of up to $20,000 for information leading to the recovery of two weapons stolen from a government vehicle,” the FBI stated in a press release today. “The weapons were stolen from an FBI SWAT emergency response vehicle.”

Andover police said the FBI had responded to a call that was made by a citizen of the town. The FBI said they were in the town, known for its prestigious prep school and low crime rate, last night into early this morning, when the guns were stolen. Police and FBI did not say what the feds were called to Andover for.

The FBI described the weapons as an M16 A1, which is an older version of the military’s classic M16, as well as a .308 caliber sniper rifle.

“All local, state and federal law enforcement agencies were quickly made aware of the theft through various means including the Commonwealth Fusion Center and Boston Regional Intelligence Center,” a press release from the agency stated.
