He had become intoxicated and rowdy and a security guard told him to leave about 12.30am. After leaving the pub the man was denied entrance to the pub to get his friends to walk home with him.

He began walking home across the old basketball courts, opposite the popular nightspot. He was then attacked from behind - hit on the back of the head.

As he lay unconscious on the ground, his car keys and mobile phone were taken. His mother said her son had not taken his wallet with him, but instead took cash, which was fortunate.

"He called the police on Saturday morning and was told to make an immediate statement," she said.

She could not find anything around the basketball courts the next day.

"The security guard knew my son because when he kicked him out he said ‘Go home, this isn’t like you’," she said.

"So I want to know why he let him leave in such a state. It just seems to me that there are regulations on how much alcohol can be given to someone, but it sort of gives the impression that once the pubs have the customers’ money, they don’t care about them."

She also said that if her son had been allowed to go back into the pub to get his friends, he would not have been attacked.
