"It was a loud bang," said neighbor Sandy Proctor.
The man was taken to Lowell General Hospital by ambulance before being flown by medical helicopter to a Boston hospital. His injuries were described by police as serious.
The officer who was hurt was treated and released from Nashoba Valley Medical Center.
Multiple neighbors say the man who was shot had a long history of mental health issues.
"The recent thing, in the last few months, he's been walking up and down the street with a stick on his shoulder, chanting, wearing some kind of a cape or blanket," said Proctor.
Neighbors say police have been to the home many times in the past.
"He's always outside. He's had a few mental health issues. Cops have come to take him to the hospital, get him some help," said neighbor Derrick Zina.
Police have not released details about the arrest warrant that brought them to the home in the first place. The man has not been identified.
"The family's a good family," said neighbor Jeff Durand. "I've been here about six years, I haven't had a problem with any of them. They've been good neighbors."
The Middlesex County District Attorney's Office is investigating the shooting.
