Police said arrests were made after protesters began throwing fireworks, bottles and rocks at officers during a protest that shut down a section of Interstate 94 in St. Paul on Saturday night.

The highway was blocked following a march that started outside the governor's mansion, where protesters have been gathering since the fatal police shooting Wednesday night of Philando Castile. The 32-year-old black man was shot during a traffic stop in suburban St. Paul while, according to his girlfriend, he reached for his wallet.

St. Paul police said on the department official Twitter account that an officer was injured by a firework thrown by protesters. Police said protesters also were throwing objects and liquids from highway overpasses.

Police said some protesters sat down after being warned they were subject to arrest if they didn't disassemble.

The number of arrests made was not immediately released. Several officers were also injured.
