Boston Police Chief Daniel Linskey

Boston police said they have video that should end any questions about whether law enforcement used appropriate force when they fatally opened fire on a 26-year-old terrorism suspect in his neighborhood Tuesday.

The Associated Press reports that Usaama Rahim lunged at a police officer and FBI agent with a military-style knife, prompting law enforcement to open fire, according to police accounts.

The man’s brother disputes the account.

The shooting happened as the Joint Terrorism Task Force went to question him about “terrorist-related information,” Police Commissioner William Evans said.

It’s not yet clear when the surveillance will be released.

Rahim, who was shot in the torso and abdomen, was pronounced dead.

A man connected with the case was arrested by the FBI late Tuesday.
