There were about 30 people involved and all are considered offenders, even those injured, Senior Sergeant Trevor Smith said on Wednesday, but police have only made four arrests.

A 16-year-old girl from Doveton was also arrested and released pending further enquiries.

Police only became aware of the Tuesday night fight when a girl took herself to hospital about 9.30pm on Tuesday. A 16-year-old was also treated for stab wounds to her back and arm and was taken to a children's hospital for further treatment. Another 17-year-old was treated for lacerations to her hand before being discharged. There was an increased police presence at Fountain Gate on Wednesday.

"A group of probably 30-odd, mostly females, in their mid-to-late teens, have gathered at a Fountain Gate reserve where a fight broke out between two parties," he said.

"It's unusual for an arranged fight by females. "I was a little bit surprised." By the time police arrived, the brawl had ended and most of the teenagers had fled. Police spoke to several witnesses, though not everyone was co-operating, he said. Workers at Fountain Gate said the shopping centre had a "treacherous" reputation, with some staff too scared to use the underground car park at night. One worker at the shopping centre said there were frequently issues of youth crime and violence.

"Every day there is something that goes on," said the shop assistant, who has worked at Fountain Gate for four years. She said there was always at least one police car in the area from the afternoon onwards. "It didn’t used to be that bad," she said. The woman said she doesn't park in the underground carpark if she's working late to avoid young people congregating there. A worker at one of the many kiosks said the centre appeared to have a "treacherous" reputation.

"If I tell people I work at Westfield Fountain Gate shopping centre they sort of scoff and say 'that must be fun'," the man said. But there's generally a high police presence to deal with any issue and he said he never felt unsafe at work. But he said it’s "not a shopping centre you feel that relaxed in". "There’s always something going on," he said. "Rarely a day goes past where you don’t see something. "It's interesting enough, you get a good front row seat."
