A man was stabbed in the chest with a key after he challenged thugs harassing his girlfriend.
Two men shouted 's**g' and 'you're sexy' at the man's partner while she was sat on the pavement on Whitworth Street West in Manchester city centre.
They then pushed her to the floor.
When the woman's partner told them to leave her alone, around six men 'jumped him'.
They threw bricks at him and kicked him during the attack, which happened at 3am on Saturday (July 27).
The man's partner, a woman in her 20s, who asked not to be named, said: "They were just picking up bricks, saying they had knives.
"They were kicking him in the face. All over his body. They threw a brick at my boyfriend. They picked up another brick as well, I pushed it out of his hand."
"I was trying to grab them off him, saying 'leave him alone'.
"They stabbed my boyfriend in his chest. He's got a hole in his chest.
"When they realised I was shouting 'help', they ran off."
