A man charged over the murder of Michelle Bright in regional NSW more than two decades ago is also facing accusations he raped a teenage girl in Sydney's west.
Michelle was last seen alive on February 27, 1999, when a friend dropped the 17-year-old off at Herbert Street in Gulgong, near Mudgee, after a birthday party.
Her body was found three days later in long grass beside Barneys Reef Road.
Earlier this year, detectives from the Unsolved Homicide Unit arrested a 53-year-old man near Mudgee.
He was charged with murder and remains before the courts.
As part of ongoing inquiries, investigators received reports a 17-year-old girl had been sexually assaulted by a man known to her at Regents Park in 2007.
Police say the 53-year-old was charged on December 2 with assault with act of indecency, attempted choking and aggravated sex assault.
He has been remanded in custody and will appear at Mudgee Local Court on Wednesday.
