Police have released CCTV in an appeal for information following a home invasion in Sydney’s west earlier this year.

On the evening of August 31 three men and a woman allegedly forced entry to a home at Boronia Street, Concord West.

Police were told the woman left the area, before the men – armed with a firearm and baton – threatened the occupants of the home.

The men allegedly assaulted a 21-year-old man, before stealing cash and leaving the area in a dark-coloured vehicle.

The woman is described as being of Caucasian appearance, aged between 18 and 20, with long dark hair, braces, large fake eyelashes and wearing a light-coloured puffer jacket.

The three men all wore black clothing.
