Police investigating a serious assault in Cumbria have arrested four men.
The 24-year-old victim, Ian Renouf, suffered facial injuries in the unprovoked attack in Cockermouth early on Sunday.
In a bid to encourage witnesses to come forward, police earlier released graphic pictures of his injuries.
Following tip offs from the public, the men, aged between 18 and 25 were been arrested on suspicion of grievous bodily harm.
Mr Renouf was treated at West Cumberland Hospital following the assault at about 0215 BST on Sunday.
He was discharged on Tuesday and is now recovering at his home in Workington.
