Boston police shoot man armed with "very large knife" at Brighton home

Boston police officers shot a man armed with a "very large knife" in Brighton Friday morning, according to the commissioner.

The officers were called to a home on Selkirk Road just after 7 a.m. for a report of a man threatening to harm himself.  Police Commissioner Michael Cox said the man refused to drop the knife. Officers spoke with him for about 20 minutes, but the man then charged at police and he was shot once in the stomach, Cox said at a news conference.

The man was rushed to the hospital and is in critical condition, the commissioner said. He has not been identified. 

Another person was inside the home during the incident but was brought out safely by officers. 

None of the police officers were hurt but two of them were taken to a hospital for evaluations. The officer who shot the man has not been identified. Cox said he's been on the force for a little more than two years. 

The commissioner said other officers at the scene had tasers but said it's not clear yet if the officer who fired his gun had one. 

The Suffolk County District Attorney's office is investigating the incident.

"We commend our officers swift response and efforts to de-escalate an incredibly dangerous and highly hostile situation that ultimately resulted in an officer having to discharge his firearm," the Boston police union said in a statement. 

"Thank goodness, our officers are okay. And, while we're grateful to learn that the suspect is expected to survive his injuries, we continue to instruct anyone having a contentious encounter or interaction with any of our officers to please comply with their lawful commands. Compliance creates a safer environment for all involved."
