Four firefighters and an off-duty Boston police officer were injured when a Boston Fire Department vehicle crashed into a bank less than a mile away from a fire scene early Thursday morning. The fire truck crashed into a Bank of America around 2:26 a.m. at the intersection of Talbot Avenue and Washington Street in Dorchester. A Jeep was also involved in the crash. Codman Square was temporarily shut down as a result of the accident scene and subsequent investigation. Boston police said the fire truck collided with another vehicle operated by an off-duty Boston police officer, who suffered life-threatening injuries. Four Boston firefighters who were in the fire truck were also taken to a local hospital but their injuries are not believed to be life threatening. Crews were battling a serious fire at Charlie's Pizza that caused an estimated $300,000 worth of damage.
