Mitchell Jack Evans, of School Road, St Clement, committed the offence in the early hours of 18 June in the smoking area outside the Havana Club while intoxicated.
The defendant was placed on the Sex Offenders Register for three years and banned from licensed premises for three months, as well as fined £300 for causing malicious damage to a pub window that he smashed.
The court heard from legal adviser Lauren Hallam that Evans was talking to two women he knew outside the nightspot at 12.30 am on 18 June when he put his arm round shoulder of one of them and squeezed her right breast.
The woman said: ‘What the f*** are you doing? Get your hands off me.’
The court heard that the woman complained that the squeeze had caused her pain.
The defendant responded: ‘I am Mitchell Evans and I can touch anyone’s t**s I want.’
Miss Hallam said that when interviewed by police the defendant could not even remember going to the Havana. The court heard that he had earlier been to the Halkett pub and his next recollection was waking up at home the following morning.
When asked about the indecent assault, he said: ‘It is a bit embarrassing but I can’t remember anything about it.’
He said that he had known both women for a number of years and had never had any problem with either of them but conceded to officers there was no reason why they should make up such allegations. Evans later pleaded guilty to indecent assault.
Miss Hallam said the complainant had confirmed that she was not seeking a restraining order against Evans.
Evans also admitted causing malicious damage to a glass window at the Earl Granville pub in Providence Street on 3 December.
Advocate Jane Grace, defending, said that Evans wanted to organise for the damage to be repaired himself as
he worked for a window company.
The incident in the pub took place when Evans was unhappy at being asked to leave, as he was heavily intoxicated.
In respect of the indecent assault, Advocate Grace said it was ‘brief touching, but not a sustained assault’ and ‘could be put down to youthful high jinks’.
She added: ‘The complainant had a justifiable outrage rather than fear.
‘She told him not to touch her breasts and she made it clear to him that his attention was not welcomed.’
