Police have arrested 130 protesters, including 60 for alleged felonies such as criminal damage to property and conspiracy to riot.

Starting at about 11 a.m. CDT Monday, protesters began to march toward the Xcel Energy Center in downtown St. Paul, Minn., where Republicans are holding their presidential nominating convention. Most of them marched peacefully, but a few groups deviated from the city-approved parade route, breaking windows and slashing tires.

Most of the 130 arrests occurred after 5 p.m., according to Holli Drinkwine, a spokeswoman for the Ramsey County sheriff’s office. Police officials expect the arrests to continue.
