GRAND RAPIDS, Mich. (WOOD) — The Grand Rapids Police Department is asking for the public’s help to identify three men believed to have been involved in a beating at Rosa Parks Circle last week.

GRPD says a group of men punched and kicked the victim, a man his 20s, in the head until he lost consciousness. He was seriously injured.

Two people were arrested last week, but police say more attackers may still be at large. On Monday, they released two surveillance images showing three suspects. GRPD is asking for help identifying the men, saying all are in their mid- to early 20s and that they likely frequent the Heartside area.

Anyone with information about the fight or the people in the photos is asked to call GRPD Detective Josh Cornell at 616.456.4459, Sgt. John Purlee at 616.456.3343 or Silent Observer at 616.774.2345.
