A retired professional fighter has turned himself into police following an alleged violent road rage attack on a father and daughter in Surfer’s Paradise that was caught on camera.

The 52-year-old father, Nathan Harris, was knocked unconscious in the alleged attack at Surfers Paradise on Saturday afternoon and his daughter was allegedly assaulted when she tried to intervene.

Daniel Valusaga, turned himself in to police yesterday and was charged with two counts of assault occasioning bodily harm.

“I’m sorry about what happened and it’s going through court at the moment,” Mr Valusaga, a former Mauy Thai Champion, told 9NEWS.

The 39-year-old from Marsden was granted conditional bail and is set to appear in court next month.

Video of the alleged attack appeared to show Mr Harris, who was in a blue sedan, being punched several times.

Mr Harris yesterday said his alleged attacker beeped at him after he was double-parked on Trickett Street.

His wife, Shayle Harris, said she watched in horror as the incident unfolded.

“The seatbelt just wouldn’t undo,” Mrs Harris said.

“When I saw his eyes rolling into the back of his head, I thought the worst.”

Mr Harris’s 20-year-old daughter was also allegedly hit in the face and suffered a swollen jaw.

Mr Harris was left unconscious on the road for about five minutes before he and his daughter were rushed to hospital by paramedics.

Mr Harris was released from hospital yesterday, while his daughter received X-rays for facial injuries.

“She can’t smile. Every time she tries to smile it hurts,” Mrs Harris said.
