MINNEAPOLIS: Minnesota state authorities are investigating after Minneapolis police shot and killed a black man they say had been firing a handgun as he walked outside.

Roughly 300 people gathered for a Sunday afternoon protest at a police station and a vigil near the north Minneapolis shooting scene was set for the evening, the Star Tribune reported. The Minnesota Bureau of Criminal Apprehension, which is investigating the shooting, said in a statement that it will release the names of the officers who shot their weapons after “both” have provided interviews.

“At the end of the day, we know that no matter what transpired in the moments leading up to the shooting, we know with certainty that the outcome is a tragedy,” Mayor Jacob Frey said in a statement. He didn’t march in a Sunday parade celebrating gay pride to focus on the shooting.

Authorities said two calls to 911 reported that a man was firing a handgun into the air and the ground. The bureau said he was sitting on a curb with a woman when police arrived, and then ran from officers while holding a black and silver gun.

Minneapolis police pursued and then shot the man, who was pronounced dead Saturday at the scene. The BCA said officials recovered a black and silver handgun from the area.

The bureau said officers’ body cameras recorded the shooting, but squad car cameras did not. Both officers are on administrative leave.

Agents are interviewing witnesses and participants in the incident. The bureau said it would perform a “thorough investigation” and turn over the findings for review to the Hennepin County Attorney’s Office.

Some witnesses have disputed the police account of the shooting, saying the man did not have a gun.

The man is the 30th person killed by police in Minneapolis since 2000, according to the Star Tribune.

The head of the Police Officers Federation of Minneapolis didn’t immediately return a telephone message requesting comment from The Associated Press.
