Fifth bikie nabbed in Central Coast sting

A bikie has been charged with commercial drug supply, making him the fifth member to be caught in a gang squad sting targeting drug dealers on the NSW Central Coast.

The 27-year-old, from Daleys Point, was arrested and charged on Monday after four other men, aged from 25 to 37, also with bikie links, were charged earlier in September with commercial drug supply offences and participating in a criminal group.

Their charges came after raids at a unit in Gosford, a semi-rural property in Picketts Valley, the 27-year-old's Daleys Point home and a house in Niagara Park.

"Over the course of the investigation gangs squad detectives have seized approximately 3.5kg of amphetamine, 1kg of methylamphetamine, 1000 PMMA tablets (an ecstasy like substance) and significant amounts of heroin," police said in a statement on Tuesday.

The 27-year-old is due before Gosford Local Court on December 12.
