A 31-year-old Sydney woman was allegedly choked and sexually assaulted in her apartment on Sunday after advertising a room for rent online.
The woman met the 31-year-old man, who had asked to inspect the property on Corby Street, Concord, just after 7am on Sunday morning.
"After entering the apartment the man allegedly sexually assaulted the woman," police said.
He then allegedly stole her car and fled, police said.
Four hours later police arrested a man at Paddy's Markets in Sydney's CBD where he was searched. Police allegedly found a key from the stolen vehicle.
The man was taken to Sydney City Police Station where he was charged with a number of offences including aggravated sexual assault; choking with intent to commit a serious indictable offence; stealing from a dwelling; two charges of common assault; police pursuit; and intimidation.
The charges relate to Sunday's alleged incident, another alleged assault of a woman at her Strathfield home on April 2, and a car allegedly stolen on March 25.
The man was refused bail and is due to appear at Central Local Court on Tuesday.
