A Sydney woman will face court accused of stabbing a teenager at the wheel of his car during an apparent ambush attack after the pair met online.
Police say the 19-year-old drove to a street at Casula, in the city's southwest, to meet a woman he had been communicating with on social media, on Thursday night.
As she entered the passenger seat, however, three armed men approached the rear of the Subaru.
As the youth accelerated to escape, the woman allegedly produced a knife and stabbed him in the stomach.
Injured, the man crashed into a parked trailer and two parked cars before fleeing his own vehicle and jumping a fence into a nearby street where he was found and helped by a resident who then dialled triple zero.
The man was taken to Liverpool Hospital and underwent surgery. He remains in a serious but stable condition.
Liverpool detectives arrested a 20-year-old woman at a home in Casula on Friday afternoon and charged her with wounding with intent to cause grievous bodily harm.
She was refused bail to appear before Parramatta Bail Court on Saturday.
