Police are investigating after a teen girl was hit by a brick at a Charlestown house party.
Officers were called to a home on Roslyn Avenue at around 8pm last night.
It's alleged a group of gatecrashers who'd been turned away from a party at the home launched sticks, bottles and a brick into the backyard of the home while leaving.
The brick struck an 18-year-old in the head, who's since received stitches in the John Hunter Hospital.
Anyone who may know more is urged to contact Crime Stoppers on 1800 333 000.
