Detectives have released CCTV images of a man they would like to trace following a serious assault in Blackpool.
Officers said a 21-year-old man was punched in the back of the head as he walked along Queen Street at around 3am.
The victim fell to the ground and hit his face on a small wall, which left him with multiple fractures to the side of his face.
Det Con Ian Massey has now released a CCTV image of a man caught on camera near the scene.
He said: “I am very keen to speak with this man, and would urge anybody who knows who he is to contact police on 101.”
The incident took place on September 29, but police have only just released details of the incident.
