The son of a Gold Coast woman who was viciously bashed during a carjacking has begged for help to catch her attackers.
Linda Cheng, 55, was pulled from her gold Nissan in a shopping centre carpark by a group of men in the early hours of Wednesday.
The slightly built woman, who had fallen asleep in her car, tried to fight back but was bashed and left bleeding on the ground of the Molendinar carpark.
She suffered cuts and bruises to her face and body.
Her son said his anger at the news of the attack turned to sadness when he saw his mum's battered face in hospital.
"I don't know how anyone could do this kind of stuff, especially to a female," Jimmy Cheng told reporters on the Gold Coast on Thursday.
He said his mother worked two jobs during the day and had meant to take a quick nap before shopping but she overslept.
"She's very distraught about what happened.
"She doesn't understand why someone would do this to anyone.
"We're just appealing to the Gold Coast public if anyone knows any information (to help) find the person who did this."
CCTV footage was unclear, but a witness told police up to seven men could have been involved in the attack.
"You could only describe them as thugs," Detective Superintendent Dave Hutchinson said of the attackers.
"For any male to do what they've done to this slightly built 55-year-old woman is just horrible.
"Obviously somebody out there knows something, and hopefully we can appeal to their better senses."
