The investigation continues into a bizarre assault in Grinnell last night. Witnesses say a man wearing a black ski mask came running of an alley downtown and attacked one man in a group of friends who were talking. He punched the victim in the ear. Police say the masked attacker had to run through the crowd to get to the victim, who was treated and released at the local hospital for a serious injury to his ear. The masked man took off on foot and they’re still looking for him.
