Massachusetts State Police are investigating an officer-involved shooting that took place in Chelmsford.
According to the Middlesex District Attorney's Office, a Tyngsborough police officer attempted to make a routine traffic stop after spotting a vehicle around 9 p.m. on Saturday evening. Authorities said the officer followed the driver down Route 3 where the man entered the parking lot of Sully's Ice Cream on Graniteville Road in Chelmsford.
When a Chelmsford sergeant approached the car, the suspect backed up and dragged the officer several yards. Authorities said the officer then struck a Chelmsford cruiser.
Fearing for the safety of that officer, a Tyngsborough officer fired his weapon, striking the man.
The suspect, a 27-year-old Tyngsborough man, was airlifted to a hospital in Boston where he was listed in grave condition.
The Chelmsford officer was taken to a nearby hospital after suffering non-life threatening injuires and was later released.
Per department policy, authorities said the Tyngsborough officer that used his weapon is currently on administrative leave.
This incident is still under investigation.
