A 26-year-old Urbandale man remained in a medically induced coma Sunday as authorities investigated the assault that injured him. Officials say the unidentified victim was beaten severely outside a Des Moines sports bar early Sunday morning. Witnesses told police the victim had been arguing with a group of men inside the bar before the assault. Police found marijuana, a concealed weapons permit and firearms in the victim's vehicle, but they haven't been able to talk to the victim. Police identified a suspect in the case with the help of a tip from the public, but the suspect has not been identified.
