Brick Hits Teen At Charlestown Party

She's been treated in hospital.

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.
