A WOMAN filmed attacking an old blind man on a bus has had her sentence tripled in Brisbane District Court this morning.

Larna Watmough, 21, was handed a two-month suspended sentence for the attack on 77-year-old Paul Buttigieg, with her friend Layni Cameron, 17, who was sentenced for three months.

Footage of the attack, filmed by a fellow bus passenger went viral after it showed the young women, dressed for the races, punching and yelling at the man.

Judge Paul Smith upheld an appeal by the Attorney General’s office, which claimed Watmough’s sentence was inadequate.

Feral bus attack A young woman who assaulted a 77-year-old partly-blind pensioner on a Gold Coast bus has been given a suspended jail sentence and slammed by a magistrate as a 'lout and an idiot.'

He set aside the two-month sentence, re-sentencing her to six months imprisonment from September 17 — wholly suspended.

Watmough must not commit another offence jailable offence within 18 month of that date or she will have to serve the suspended term.

Viral footage of the attack showed the women embarking on an obscene tirade before Mr Buttigieg told the pair to “get off the bus” and “go back to where you came from”.

The comments enraged the girls, with the footage showing the girls punching, slapping and kicking the helpless pensioner as they chant obscenities and Cameron tells him to “go back to Abo land”.

At one stage, Mr Buttigieg attempted to fend the girls off, but this only served to escalated the assault and Cameron spits in his face.

Passengers stepped in and called on the girls to “leave the old bloke alone” as children on the bus began to cry.
