ST. PAUL, Minn. (AP) - St. Paul's city attorney says he's considering charges of rioting against 50 people arrested in a weekend protest on Interstate 94 over the death of Philando Castile, who was shot by a police officer.

City Attorney Samuel Clark says his office is reviewing evidence from the protest, including photos and video, to determine whether there's sufficient evidence for charges. The Minnesota State Patrol arrested and booked the 50 individuals on a possible gross misdemeanor of third-degree riot.

Clark says the protesters endangered others when they walked onto the interstate and refused officers' commands to leave Saturday evening.

After the interstate arrests, police stopped protesters walking in the road on Grand Avenue early Sunday and arrested 52 people. They were cited for public nuisance and unlawful assembly and released.
