And Fergus Wood, of Invergare House, Rhu, has been given time to further his rehabilitation after having his sentence deferred for good behaviour.

Wood admitted to two charges of assault at Dumbarton Sheriff Court on Tuesday after he became aggressive at the bar in Helensburgh in June.

The 23-year-old had been in the bar drinking when he approached staff looking for more alcohol, however, they had already made the decision he would not be served further.

After he was told, Wood “paced back and forth” and was “staring” at witnesses.

Jeanette McLean, prosecuting, told the court: “The male member of staff told the female member to ignore him and he would go away.

“However, she was struck on the face by a bit of ice thrown by the accused.

“She was shocked by this and he was standing next to the ice bucket and said, ‘I didn’t do anything’.” Door stewards were then called to remove Wood and as they did police officers walked by on Clyde Street. They stopped to assist but found Wood to be in an “aggressive state”.

As officers tried to put him into the rear of a police van Wood tried to headbutt an officer on the head.

En route to the police station, Wood repeatedly banged his head against the cell door, causing an injury.

This required officers to take him to the Western Infirmary to have the wound on his head glued.

Ms McCrae, defending, said her client accepted his level of “intoxication was too much,” leading him to realise there was an underlying problem. She said her client was so drunk he didn’t know what had happened when he woke up in the police cell.

Ms McCrae added: “It’s had a beneficial effect in that he has addressed his issues of drinking. He also wrote a letter to the bar staff apologising and sent flowers to the female member of staff before any contact with my office.

“The wording of the letter shows he understands how inappropriate his behaviour was.” Continuing to address the problem, Wood went to his GP to seek a referral to an addiction service and has since been working with Heart and has stopped drinking completely.

Ahead of starting a course in Digital Film Production at Ravensbourne University in London this September, Wood has sought a referral from Heart to a similar service in England to help him continue addressing his drinking.

Sheriff Colin McKay said: “It’s quite clear that you have well recognised the problem and are dealing with it seriously.” Sentence was deferred until February 17.
