A group of about 20 to 30 vandals, dressed in black and wearing masks, committed multiple acts of vandalism just after 11 p.m. last night.

The group, which some witnesses described as looking like "ninjas," damaged the windows of several businesses and vehicles near the East Side intersection of Farwell and North Avenues, threw construction barricades into the street and set off smoke bombs in the streets.

Milwaukee Police said that the following businesses reported broken windows:

U.S. Bank, 2303 N. Farwell Ave.
Whole Foods, 2305 N. Prospect Ave.
Qdoba, 2228 N. Prospect Ave.
Bruegger's Bagels, 2045 E. North Ave.

Milwaukee Police are looking into whether this activity was related to a protest earlier in the evening by a group of self-titled "anarchists" in the Riverwest area, department spokesperson Anne E. Schwartz said. There is no one in custody at this time, but some suspects were seen leaving in a green 1992 Honda Civic, license plate 547-HGH.

If anyone has information on that vehicle or on the incidents, please call Milwaukee Police. The number is (414) 935-7253.
