MINNEAPOLIS (AP) — Demonstrators blocked traffic on a busy highway in north Minneapolis to protest the police shooting of a black man over the weekend.

Media reports say the protesters headed to Interstate 94 and shut down the northbound lanes Monday evening after rallying at a police precinct.

Some protesters are camping out at the Minneapolis police 4th Precinct office, near where 24-year-old Jamar Clark was shot in a scuffle with officers. The protesters are vowing to continue their occupation, calling for the release of any video authorities have of the incident and the names of the officers involved.

Mayor Betsy Hodges has requested a federal civil rights investigation.

Clark was taken to a hospital after the shooting, and his family says he is on life support.
