A woman found herself the victim of unwanted attention after a stranger slapped her bottom saying he had to do it because her “bum was too nice.”

Jesse Ratu, a 24-year-old mum of two was returning from a morning walk to her apartment in Southport, Australia when the man followed her to the front door and proceeded to slap her repeatedly on her bottom.

The whole incident was caught on CCTV and police are now hunting for the attacker, Yahoo Style UK reports.

“I just buzzed, and that’s when he grabbed my bum, like five times, and I think I said, ‘Don’t touch me’,” she said.

“He said to me, like, ‘Sorry, I just had to do that, you’ve got the best bum’… That’s when I just pushed the door open and freaked out,” she said.

Once inside her apartment building, Jesse said it took her a few moments to realise the extent of what had happened, before running upstairs to tell her partner who was inside with the couple’s children.

Jesse’s partner came down to see if he could find her attacker, but after failing to spot him, the couple called the police and Ms Ratu lodged a complaint.

Senior sergeant Brendan Wiblen of the Gold Coast Police said that, while assaults of this nature are not common, authorities are taking the offence very seriously.
