"The more serious offence was fetching the gun and using it to frighten Miss Morgan. Yes, it was not a real gun, but she didn't know."

Nicholas Fridd, prosecuting, told Bristol Crown Court: "This arose because it came to the attention of Jacqueline Sandic that her husband had spent the night with the victim.

"She and the defendant went to deal with the matter.

"They went to the Bristol House Hotel and they entered the bar. Jacqueline was only charged with battery and is being dealt with in the magistrates' court.

"A gun was produced and the defendant was arrested the next day. He made a full explanation in his second interview, after he had been shown the CCTV.

"He said (the gun) was a cheap £3.99 plastic thing, not a real gun."

Laura Mather, a probation officer, said Sandic received a telephone call from his mother at 8am, saying his father had not come home.

She said: "She was concerned and she wanted his help. He said his father can have issues with 'going off on a bender'."

Sandic, who engaged in cage fighting on a monthly basis, told the court: "I want to say I am sorry. I'm deeply remorseful for what I've done.

"If you do give me a chance I won't let you down. I was young and reckless."

Miss Mather added: "On the one hand he sees what he did as serious. On the other hand he doesn't see himself as posing any risk.

"It is my view he continues to pose a high risk of serious harm."

Mr Aullybocus said father-of-two Sandic had over-reacted and his intention had been simply to scare.
