Police have released CCTV images of a man wanted for questioning in connection with a serious assault on a teenager in a Chester nightclub.

The 18-year-old male victim, from Chester, was left with a bleed on the brain after being attacked inside Cruise nightclub, St John Street, Chester, about 2.30am on Tuesday, January 28.

He was attending a student night when he is believed to have been pushed down stairs and then assaulted as he lay on the floor in an unconscious state where he was later discovered by nightclub staff.

It was several days later before the victim sought medical attention, after feeling unwell. He went to hospital and was found to have suffered a bleed on the brain.

He was treated and is now home and recovering. Police were notified of the offence on January 31.
