A yob broke a man's jaw in two places as he tried to separate a fight outside a nightclub.
Jordan Yates, 23, hit his victim, Hayden Morris, so hard he caused a double jaw fracture and left him with permanent numbness in his lower lip. Liverpool Crown Court heard there were issues between Yates and the victim's friend, John Atherton, about a woman which led to the pair being kicked out of The Imperial club in St Helens.
They continued squaring up to each other outside and Mr Morris stepped in to intervene. He was concerned his friend was drunk and alone, and Yates had other men with him, said David Birrell, prosecuting.
