PORTLAND, Ore. (AP) — Police in Portland, Oregon, arrested three people during a protest decrying the fatal police shooting of a 17-year-old black teenager last month.

The protest Wednesday briefly shut down a city building where the City Council was trying to meet and halted light rail service.

Sgt. Pete Simpson says officers took reports of two assaults and property damage inside the city building.

A Multnomah County grand jury concluded last week that Officer Andrew Hearst was justified in shooting Quanice Hayes three times after police say Hayes reached for his waistband instead of following orders to surrender.

Police confronted Hayes on Feb. 9 after he allegedly used a replica gun to rob a homeless man of his state food benefits card. Hayes was also suspect in a reported car prowl shortly after the robbery and tried to enter a nearby home.
