A man has been charged with the murder of a woman whose body was dumped in bushland some time ago.

The man, 47, was taken into custody in Hobartville, about 20 kilometres from the crime scene in Werrington in Sydney’s outer west on Monday evening.

He was refused bail to appear in Penrith Local Court on Tuesday.

The 47-year-old woman, identified as Leanne Akrap, was found on Sunday in the reserve.

She was discovered lying next to clothing and rubbish.

Police had established two crime scenes after officers were called to the reserve off Irwin Street at Werrington.

Forensic teams the area, which is near sporting fields and homes, and checking bins on the street for clues.

They also searched the unit about 500 metres away from where Akrap’s body was found.

A passerby discovered her body.

“It appears as though that body has been there for a period of time without discovery,” Detective Superintendent Trent King said.

NSW Police have not yet revealed a cause of death.
