A man is in a serious condition in hospital in Greenock after he was stabbed while walking with two female friends.
The 25-year-old victim was on Wellington Street about 12.15am today when he was attacked.
The man was rushed to Inverclyde Royal Hospital and is said to be in a serious, but stable condition.
The women were both uninjured, but have been left extremely distressed by what happened, police said.
The incident is being treated as attempted murder.
The suspect is white, around 6ft tall, with a slim build.
He was wearing a black hooded top and black tracksuit trousers and ran off towards Greenock Health Centre after the attack.
