A mother who drove her two boys to a knife fight in Sydney's west has been charged, along with her sons, over the stabbing of a teenager.
A 16-year-old boy was stabbed during a fight on the front lawn of a house in south Penrith about 4.15pm (AEDT) on Thursday, leaving him with wounds in the chest, face and abdomen, police say.
He was taken to Westmead Hospital in a serious but stable condition.
About two hours later, a 49-year-old woman and her sons aged 16 and 17 turned themselves in to police at Parramatta.
A police spokeswoman told AAP the mother allegedly drove the boys to the fight and gave them a lift after the attack.
All three were charged with wounding with intent to cause grievous bodily harm.
Bail was refused for the boys who are due before Parramatta Children's Court on Friday.
Their mother was also refused bail and will appear before Penrith Local Court on Friday.
