Police are investigating an aggravated break-in at a Wollongong unit yesterday morning in which a young woman claimed an armed man tried to sexually assault her.
The teenage victim told police she was at her Smith Street unit at around 3.30am when she was confronted by a man, who was armed with a knife.
He threatened the 18-year-old before holding her down and attempting to sexually assault her.
The woman screamed out for help and the man fled, stealing a mobile phone before running out of the unit and heading north across Smith Street.
Wollongong Police attended the unit and established a crime scene which has been examined by specialist forensic officers.
Police say the woman was not physically injured during the incident.
The attacker is described as being aged in his mid 20s with a tanned/dark complexion, 175-180cm tall with a medium build, short dark hair, brown eyes and a wide, flat nose.
He was wearing a distinctive black t-shirt with a block-style coloured pattern on the front.
Investigations into the matter are continuing and anyone with information that could assist with inquiries is urged to contact Crimestoppers on 1800 333 000.
