A 22-year-old who slit another man's throat after a drinking session in Greater Manchester has been jailed.
Mark Coulburn, of Colshaw Road, Newall Green, used a Stanley knife to slash his victim, narrowly missing an artery.
He admitted wounding with intent and was given an indeterminate sentence for public protection (IPP) by a judge at Manchester Crown Court on Tuesday.
Coulburn, described as a "violent lout" by police, must serve at least six years and three months before parole.
The 23-year-old victim was attacked in a subway near a supermarket in Ashton-under-Lyne on 4 June after he spent the day drinking with Coulburn.
Greater Manchester Police (GMP) said the man suffered a cut across his Adam's apple that required 120 stitches and came within 2mm of a major artery.
Det Con Martyn Kendall, of Tameside CID, said: "The victim thought he was going to die and given the nature of his injuries it is fortunate he didn't.
"This was an unprovoked attack and the level of violence used was utterly shocking.
"Moments before slitting the man's throat he urinated and assaulted another man for no reason other than he is a violent lout.
"Coulburn is clearly an extremely dangerous man and I am pleased he will now spend many years behind bars where he can no longer pose a threat to the public."
Coulburn also pleaded guilty to section 47 assault and possession of a bladed article.
