A man is critically ill in hospital after he was stabbed in the street while walking home from a pub.
Police said the 29-year-old man had been at the Crow's Nest pub in Glenfield Road, Leicester, on Friday evening, where he was involved in an "altercation".
Later, he was walking home and was at the junction of Henley Road and Fosse Road North when he was assaulted, shortly before midnight.
Yesterday, police said the victim had "sustained stab wounds" and that he was being treated at the Leicester Royal Infirmary.

Henley Road resident Rita Williams, 75, said she saw the man falling to the ground.
She said: "I saw the poor lad fall to his knees. Then he keeled over right next to the phone box.
"I didn't know whether to go out to him or what but there were other people around and two lads who seemed to be with him.
"Then the ambulance came and took him away and the police closed the road.
"I was really worried he was dead. As long as he's alive, that's a good thing. But it's very sad."
Rita said she believed the attack was connected to shouting in the nearby Fosse Recreation Ground.
She said: "The reason I'd got up was the shouting in the park. I've got a pair of binoculars because there are always things going on in the park. It's never dull around here."
On Saturday morning the area outside the recreation ground was cordoned off by police and detectives were making door- to- door inquiries.
One Henley Road resident, who did not want to be named, said on Saturday: "I got up this morning and the police had all the blue tape up and they came round asking about what had happened. It's really awful."
Detective Inspector David Swift-Rollinson said he was keen to speak to anyone who witnessed the assault or the altercation earlier in the evening at the Crow's Nest.
He said: "We believe the injured man was involved in an altercation in the Crow's Nest at some point during Friday evening and that this may be linked to this assault.
"We believe there may be a number of people who saw this altercation and assault and we are particularly keen to speak to these people.
"Anyone with information is urged to contact police as whatever they may know could assist our enquiries."
Anyone with information is asked to contact Detective Sergeant 0683 Jim Hatton on 101 or Crimestoppers on 0800 555 111.
