Two men have been charged after a series of police raids uncovered two drug labs, including one in a secret room inside a Sydney home.

The men, 57 and 48, are due to face Parramatta Local Court on Saturday for various offences, including supplying prohibited drugs.

NSW’s anti-bikie police unit, Strike Force Raptor, led Friday’s raids after they received tip-offs in June about a fraud syndicate linked to drug manufacturing.

On Friday morning police searched homes in Earlwood, Haberfield and Drummoyne as well as a storage facility in Gladesville.

The 57-year-old was arrested at the Earlwood home, where police found a drug lab concealed in a secret room.

They also discovered six litres of liquid methylamphetamine, cocaine, ammunition, mobile phones and electronic equipment.

In Drummoyne, police arrested the 48-year-old and seized from his property methylamphetamine, cocaine, MDMA and more than $35,000 cash.

Later on Friday police searched a Homebush property where they found a second drug lab in a shed out back.

Investigations are ongoing.
