NSW Police have released an image of a man they believe may be able to assist with their investigation into the sexual assault of a 14-year-old girl who was groomed online.
Police said detectives from the State Crime Command's Child Abuse Squad began an investigation after receiving information the teenager had been sexually assaulted by a man she met online.
The pair began engaging online in early 2015 when the girl was 14 years old.
Police said they met on a number of occasions at an oval in the northern Sydney suburb of Hornsby Heights between February 2015 and January 2016, and had sex.
Child Abuse Squad Commander Acting Superintendent Peter Yeomans said despite extensive inquiries, detectives had not been able to identify the man involved, and had released the image of a man they believed could assist.
"The man is depicted as being of Asian appearance, aged between his mid 20s and mid 30s, having a medium build, with short black hair, brown eyes and clean shaven," he said.
"He may be named or used the name 'Alex', wears glasses and was known to wear business-style clothes.
"I urge members of the community to look closely at the image and if you recognise the man, please contact police."
Acting Superintendent Yeomans said the case provided a timely reminder for parents to warn their children about online safety.
"Any app, online game, or social media platform that allows the user to be in contact with someone they've only met online, potentially puts them at risk," he said.
"Not only should young people be very careful about providing personal details to a person they only know in the online environment, they should never organise to meet as doing so may place them at further risk of harm."
