Humberside Police are appealing for information.
Humberside Police are appealing for information after a man sustained serious facial injuries following an alleged assault in Howden last month.
The 24-year-old was struck from behind outside the Howden Ams pub on Market Place around midnight on Saturday December 29th.
The blow knocked him unconscious, which caused him to fall to floor to sustain injuries which will require surgery.
The victim didn't see the person, and so wasn't able to provide a description.
