A member of the Lone Wolf bikie gang has been arrested after being allegedly caught with the drug ice.

The 30-year-old man was stopped by police at Roselands, in Sydney's southwest, at 4pm yesterday while he was wearing full motorcycle group colours.

He was arrested at the scene on King Georges Road after a computer check revealed he had outstanding warrants for traffic matters.

A search found an alleged 20 grams of ice on him.

He was taken to Surry Hills police station where he was subsequently charged with supplying an indictable quantity of a prohibited drug and possessing a banned drug.

The man was refused bail to appear at Parramatta Bail Court today.
