MINNEAPOLIS — State investigators looking into the fatal shooting of a black Minneapolis man by police during a scuffle have several partial videos of the incident but won’t release them at this time, despite demands from protesters, an official said Tuesday.

Jamar ONeal Clark, 24, died Monday evening, a day after he was shot by police during an early morning dispute, the state Bureau of Criminal Apprehension said Tuesday.

Some witnesses said Clark was handcuffed when he was shot. Police initially said he was not handcuffed, but authorities later said handcuffs were at the scene and they were trying to determine whether Clark was restrained. His death sparked protests, including one Monday night in which hundreds of people blocked traffic on an interstate highway, leading to 42 arrests.

The BCA is investigating the case, and federal agencies agreed Tuesday night to Mayor Betsy Hodges’ request for a civil rights investigation. That satisfied one of the protesters’ demands, but investigators haven’t met two others: the release of any video and the identities of the officers involved.

The federal investigation will be conducted by the FBI and will be concurrent to the BCA’s probe. In a statement, federal authorities asked for cooperation from any witnesses and urged calm during the investigation.

Police said the incident began when they were called to north Minneapolis around 12:45 a.m. Sunday following a report of an assault. When they arrived, a man was interfering with paramedics helping the victim, police said. Officers tried to calm him, but there was a struggle. At some point, an officer fired at least once, hitting the man, police said.

BCA Superintendent Drew Evans said at a news conference Tuesday that investigators have video from several sources, including an ambulance, a mobile police camera stationed in the area, public housing cameras and citizens’ cellphones.

But he said none of the videos captured the entire incident and none will be released while the investigation is ongoing to avoid possibly tainting it.

Authorities have said the officers involved weren’t wearing body cameras. Evans said there is no police dashcam video of the shooting. He declined to release any identifying information about the officers, including their race, pending interviews with them.

When asked if the video shows whether Clark was handcuffed, Department of Public Safety spokesman Bruce Gordon reiterated that the video captures a portion of the incident but not everything.

He said officials can’t discuss specifics because it could potentially taint witness statements.
