Police in Minneapolis say they have an update in an investigation tied to the fatal shooting of a black man last year.

Jamar Clark died in November in a confrontation with two white officers on the city's north side. The 24-year-old's death set off weeks of protests, including an 18-day tent encampment around the area's police precinct. Neither officer was charged.

Police say they'll release information Friday on their internal investigation. No details were immediately released.

Some witnesses said Clark was handcuffed when he was shot. But investigators say the officers tried but failed to handcuff Clark, who was shot in the ensuing struggle after one officer shouted that Clark had his hand on an officer's gun.

The local prosecutor and the U.S. attorney in Minneapolis declined to file charges.
