Accused in custody over Sydney stab death

A man accused of murdering a man whose body was found inside a Sydney bedroom will remain behind bars.

Trent Errington, 29, and a 23-year-old woman were arrested at Central Station on Monday morning about 12 hours after police found the body of a 26-year-old man at a unit in Hebersham in Sydney's west.

Errington was later charged with murder and for outstanding warrants on a stalk and intimidate charge and using a carriage service to threaten to kill.

He did not apply for bail when his matter was mentioned at Central Local Court on Monday and it was formally refused.

He is set to re-appear via AVL in October.

Police say the 23-year-old woman is still assisting them with their inquiries.
