A police-involved shooting is under investigation in Chelmsford, Massachusetts.
According to the Middlesex District Attorney's office, the shooting happened at a home on Clover Hill Drive at about 7:40 a.m. Sunday.
Officers responded to the home after receiving a 911 call from an older man who heard other family members — a man and woman — engaged in some type of altercation, according to Chelmsford Police Chief James Spinney.
"He was concerned for their well-being," Spinney said.
According to the Chelmsford Police Department, the suspect became combative with the responding officer and struck him in the face with a closed fist.
During the altercation, two additional Chelmsford officers arrived at the scene. The suspect continued to be combative, using a large shard of glass and a hammer as weapons.
After officers tried repeatedly to control the suspect, a Taser was used. When that was not successful, another officer discharged a firearm.
"There was one Taser deployment and it was ineffective. At that point, with growing concern for the well-being of that female and that male victim who was in close proximity to that male subject, the officer discharged his firearm," Spinney said.
Police said they had responded to the home a number of times within the last six months.
Authorities said the officer who discharged the firearm is on administrative leave pending the outcome of the investigation.
The names of the suspect and victims have not yet been released.
The suspects wounds are believed to be non-life-threatening, however he remains in serious condition. He is expected to face charges in connection with the incident.
The female victim was also transported to a hospital where she is being treated for injuries allegedly caused by the suspect during the altercation.
