The incident occurred at about 10:50pm on Shellharbour Road, near Sunset Avenue, Barrack Heights. The teenager was walking when she was struck by an e-bike. Ambulance crews treated her at the scene before she was airlifted to St George Hospital in Sydney in a critical but stable condition.
Police spoke with the male rider, who stayed at the scene. He was given a breath test, which allegedly returned a positive reading. He was then arrested and taken to Oak Flats Police Station, where a second breath test reportedly showed a reading of 0.135 — more than two and a half times the legal blood alcohol limit for driving a motor vehicle. Police also allege he returned a positive result to cocaine and methylamphetamine. The samples will undergo further analysis.
No charges have been laid at this stage. Police seized the man's e-bike for forensic testing.
Police are searching for a second e-bike rider who was in the area at the time and left without stopping. They urge that person, or anyone with dashcam or mobile phone footage, to contact Oak Flats Police Station or Crime Stoppers on 1800 333 000.
