A woman is in hospital after falling from a balcony following an alleged assault in Sydney.

Emergency services were called to a unit complex on John Street, Waterloo, at about 6pm on Sunday in response to reports of an assault.

According to police, a 31-year-old woman allegedly fell from an upper level into the courtyard of a ground-level unit but managed to walk away from the scene.

About an hour later, she was located in nearby George Street with head injuries by a member of the public who contacted emergency services.

The woman was treated at the scene by NSW Ambulance paramedics and taken to St Vincent’s Hospital in a stable condition.

Shortly afterwards, a 35-year-old woman arrived at the same hospital, claiming she had also fallen from a balcony in Waterloo.

Police are investigating if the incidents are connected.

Anyone with information about either incident is urged to contact Redfern Police Station or Crime Stoppers on 1800 333 000.
