MINNEAPOLIS (AP) — Minneapolis police say several officers sustained minor injuries during a protest over the shooting of a black man by an officer.

Inspector Mike Friestleben told the Minneapolis Star Tribune that the officers were hurt Wednesday night after being hit by water bottles and rocks. Scores of protesters had gathered outside the 4th Precinct headquarters, near where 24-year-old Jamar Clark was shot Sunday. He died a day later.

Friestleben also says police arrested one man on suspicion of slashing the tires of an unmarked squad car.

Police told TV station WCCO several squad cars in the precinct parking lot sustained "significant damage" from bricks.

Minneapolis Mayor Betsy Hodges issued a statement saying she and police Chief Janee Harteau urged officers to exercise restraint and protesters to act peacefully.

Minneapolis police are using a chemical irritant to control a crowd of protesters outside a precinct office near where an officer shot an unarmed black man over the weekend.

Police spokesman John Elder says chemical spray has been coming from both police and the crowd.

Scores of protesters are massed outside the 4th Precinct headquarters in north Minneapolis. Earlier Wednesday, police cleared the entryway where demonstrators had camped out since the shooting of 24-year-old Jamar Clark early Sunday. Clark died a day later.

According to tweets from the Minneapolis Police Department, police used a chemical irritant after officers trying to remove tarps had rocks and bottles thrown at them. In another incident, police say an officer was hit by an irritant sprayed by a protester.

Police say they also have fired one marking round to identify a man who was throwing bricks.

MINNEAPOLIS (AP) —  Police in Minneapolis say a move against protesters camped out at a north side precinct was limited to clearing its entryway of demonstrators.

Some 18 tents have been set up outside the 4th Precinct in the wake of Sunday morning's fatal shooting of an unarmed black man, 24-year-old Jamar Clark. Some protesters had been sleeping in the precinct vestibule.

Chief Janee Harteau says officers warned four women they had to leave the building's vestibule or be arrested. She says police have no plans to clear away the tents or stop protests as long as they are peaceful.

Inspector Michael Friestleben says officers have shown restraint as bottles and rocks have been thrown at them.

Authorities have identified two Minneapolis police officers involved in the weekend shooting of an unarmed black man.

The Bureau of Criminal Apprehension says they are Mark Ringgenberg and Dustin Schwarze. The state agency says both have been police officers for seven years, including 13 months with the Minneapolis department.

The BCA is investigating circumstances surrounding the death of 24-year-old Jamar Clark, who died Monday after being shot once in the head. Police say Clark scuffled with officers who had been called to the scene of a suspected domestic assault. And they say Clark, a suspect in that assault, was interfering with emergency workers trying to treat the victim.
