A Metropolitan Police officer was arraigned in Middlesex Superior Court House this week for allegedly shooting at two off-duty officers on Tuesday.
A police officer said that John T. Moquin, 42, was also off duty when he allegedly fired a handgun at another Metro officer and a Cambridge Police officer at the Veterans of Foreign Wars (VFW) post in Cambridge.
Metro Police spokesperson Brian Hermes said an argument between Moquin and the other two officers at a VFW meeting last month led to Tuesday's shooting.
Neither office was injured by the gunfire.
Moquin, an 11-year police force veteran, was released on his own recognizance after posting the $50,000 bail. He has been placed on administrative probation pending the completion of an investigation, Hermes said.
