A synthetic drug lab has been busted by RCMP in Burnaby.

The lab was found in the basement of a home in the 8200-block of Manson Drive.

Two men and a woman were arrested.

RCMP would not put a dollar figure on what they found but describe the operation as "huge" and said such labs can be very dangerous to people living near them.

Investigators said they anticipate it'll take days for officers to load and gather all of the evidence.
