A MAN faces prison after sexually assaulting a woman outside a Southampton bar in a late night, drunken attack.

Tomasz Adam Boron twice attempted to touch his victim below the waist with his hand as she waited outside The London Hotel, on Oxford Street.

As she pleaded with him to stop, the 38-year-old grinned as the woman took a picture of him to give to police.

Southampton Magistrates' Court heard Boron had been out drinking with his colleagues but made a "horrible mistake" when he tried to get close to the woman.

Prosecutor Ryan Seneviratne told the court all options should be open to the court when considering what Boron's sentence should be - including prison.

He said: "This was a serious sexual offence on a stranger outside a bar...when bouncers at the bar saw what happened they asked him to leave.

"The woman shouted at Boron twice to stop and that's when the bouncers became involved."

The court heard that the following morning Boron woke up with "a big headache and a hangover" as he began to piece together what had happened the previous night.

Will Day, mitigating, said: "He made a horrible mistake and has committed a very nasty offence on that young lady.

"He will accept any punishment for his actions.

"He is sorry and deeply ashamed by his behaviour."

Mr Day added that once the police were called by the victim, Boron waited for them to arrive and was arrested outside the bar at around 10.30pm on August 4.

In his interview, Mr Day said, Boron, of Millbrook Road East, Southampton, admitted attempting to sexually touch the woman.

He also told the court that while Boron was waiting, the victim took pictures of him, in which he was smiling at her.

During his hearing, Boron pleaded guilty to sexual assault on a female.

He will now sign on to the sex offenders' register.

A pre-sentence report detailing Boron's behaviour will be compiled by members of the probation team before he is sentenced at the same court next month.
