Police are investigating after a man was assaulted out the front of a unit block on Hythe St, in Mt Druitt, on Monday. About 3.30am, the 19-year-old man was walking home to the unit block when he heard a noise from the visitor’s carpark and went to investigate. Finding no one around, he continued towards his unit when he was struck from behind. He became disorientated, but saw a man walking away. He then approached a security guard at a nearby construction site for help.
