Pictures released of St Austell assault victim
A man has suffered a broken neck and bleeding to the brain in a "violent assault" in Cornwall, police say.
The victim was attacked while in the Gover area of St Austell between 23:55 BST on Sunday and 06:00 on Monday, Devon and Cornwall Police said.
The 38-year-old is being treated at the Royal Cornwall Hospital in Truro.
Officers said they had taken the "unusual steps" of releasing pictures of the victim to show the "shocking and serious nature" of his injures.
The man was walking along Trenance Road, near Blowinghouse Hill, when he was attacked.
As well as his broken neck and brain injuries, the victim also sustained a fractured eye socket, plus cuts and bruises.
Insp Ed Gard, of Devon and Cornwall Police, said: "He was walking home after a night out when he suffered these injuries.
"We also believe that he remained unconscious for quite some time before being discovered."
Officers have appealed for witnesses.
