A teenage girl has been left scarred for life after she was beaten unconscious by two men armed with bottles.
Kerry Quinn (pictured) suffered a fractured jaw and lost eight teeth in the attack, which police described as "vicious and unprovoked".
Her mother Kay Archer, of Allcroft Road, Tyseley, said: "She had to have an operation to fix her jaw and they had to remove two teeth which had become embedded in her cheek.
"We're all devastated by what's happened. She's had to have loads of stitches."
The 18-year-old's ordeal began after she left home to meet up with some friends in Shirley, Solihull, last Friday.
At around 11.30pm, the group separated and while Kerry and a few of her friends made their way to Shirley Park, the others went to Big John's chip shop on the nearby Stratford Road.
Police say a fight broke out in the chip shop between Kerry's friends who then left the shop and made their way back to the park. About an hour later, two men pulled up in a car prompting the teenage boys in the group to run off.
"They thought the girls would be all right, that they wouldn't attack them, but they were wrong," said Mrs Archer, who has three other children aged 21, 19 and seven.
"Two men walked up to Kerry and asked where the boys had gone. They'd been overheard saying if they couldn't get the boys, they'd slash the girls.
"So Kerry told them they couldn't go around slashing girls, at which point one of them smashed a bottle over her head and the other one rammed a glass bottle into her face."
The teenager, who works at Antony's hair salon in Hall Green, collapsed.
The teenager was taken to Heartlands Hospital and later transferred to a specialist unit at Selly Oak Hospital where she underwent surgery on Sunday to repair her jaw.
"She came out of hospital on Monday but has got to go back. She's lost the feeling in her lips and tongue and they don't know if she'll ever get it back," said Mrs Archer.
