Wolverhampton, England, police said the men, ages 20 and 27, were dressed as festive elves Friday night when they allegedly attacked a man at the Babylon Bar and allegedly assaulted a second man just before 1 a.m. Saturday outside the Civic Hall.
Police said they arrested the two men near the scene of the second attack.
The men were released on bail while police continue their investigation.
We are keen to hear from anyone who may have witnessed either of these attacks," Police Constable Tim Gee said. "In particular we would like to speak to a man who came to the aid of the man attacked in the Babylon Bar. The good Samaritan was wearing a white T-shirt and walked the victim to Queen Square to get medical attention."
