Two bikies have been charged with multiple offences after cops found police uniforms, name badges, a notebook and a mass of stolen cosmetics at a house in Sydney's west.

They also uncovered a treasure trove of guns and drugs.

Detectives raided the property in Chesham Street, St Marys about 1.30pm (AEST) yesterday.


As well as the police paraphernalia and the 1174 items of cosmetics, police also found a loaded sawn-off shotgun, bullets, amphetamines, crystal meth, hydroxybutanoic acid (GHB) and cannabis.

A 30-year-old man said to be part of the Rebels Outlaw Motorcycle Gang and a 27-year-old man said to be with the Lone Wolf bikies were charged with multiple offences, including unauthorised possession of a police outfit.

The 30-year-old is due at Penrith Local Court today while the younger man is due at the same court on October 20.

A third bikie, aged 46, also found himself in trouble for making too much noise after turning up during the raid on a Harley Davidson.

Police defected his bike and booked him for having an expired registration sticker.
