A Dee Why bus stop assault on Saturday night has left a young woman injured and a teenage boy in police custody, after a confrontation at one of the suburb’s busiest transit points escalated into physical violence.
Just before 9.45pm on 4 July, NSW Police were called to the northbound B-Line bus stop on Pittwater Road — a stop located just metres from Dee Why Police Station on St David Avenue. Officers from the Northern Beaches Police Area Command were on scene quickly and were told that a 17-year-old male had allegedly assaulted a 27-year-old woman.
According to witnesses who spoke with the Northern Beaches Advocate, the trouble started among people getting off a bus. A verbal argument broke out and then took a violent turn, with the teenager allegedly throwing the woman to the ground.
The woman suffered minor cuts to her face but declined further medical treatment at the scene. It is understood she was with at least a couple of people she knew when the incident occurred. The teenager and the woman are not believed to have known one another beforehand, and observers at the scene indicated that alcohol may have been a factor.
Police arrested the boy and took him to Manly Police Station, where he continued to assist with inquiries. A NSW Police spokesperson confirmed the matter remains under investigation and that no charges have been laid at this stage.
The area around the bus stop is understood to be well covered by CCTV, which police will review as part of their investigation. Depending on what the footage shows, officers may consider charges including assault occasioning actual bodily harm under Section 59 of the NSW Crimes Act — which carries a maximum penalty of five years’ imprisonment — or the more serious charge of affray under Section 93C, which carries a maximum of ten years. The affray charge is generally applied where conduct in a public place would cause a reasonable person present to fear for their safety.
Because the alleged offender is 17, any action taken against him would be handled within the framework of the NSW Young Offenders Act 1997. That legislation covers young people aged between 10 and 17 and recognises that they should not be treated the same as adults when they break the law. Among its guiding principles is that the least restrictive form of sanction should be applied, and that criminal proceedings should not be commenced against a child if there is an alternative and appropriate means of dealing with the matter. Under the Act, police may divert a young offender away from court through a warning, a caution, or a referral to a youth justice conference — but only if the young person has admitted the offence and consented to diversion, and if they are eligible for it. Whether any of those pathways apply will depend on the evidence gathered and the seriousness with which police ultimately view the alleged conduct.
The B-Line stop at Dee Why is one of nine stops on the B1 route, which runs between Mona Vale and Wynyard Station in Sydney’s CBD and is operated by double-deck buses. It is a busy interchange point, with connections to local bus services throughout the Northern Beaches.
Anyone with information about this incident is urged to contact Northern Beaches Police Area Command or Crime Stoppers on 1800 333 000.
