VANCOUVER -- A clandestine drug lab was dismantled at a rural, residential property in Langley Thursday, Mounties say.

There was a significant police and emergency response presence near 21B Avenue and 248 Street as investigators secured the property to safely execute a search warrant. 

Police say "evidence of pre-cursor chemicals" were found at the lab and that further testing will be done. 

"The investigation will continue to determine what charges, if any, will be laid," Mounties said in a news release. 

The Township of Langley Fire Department and BC Ambulance Service were also on scene in case of emergency and drivers were temporarily asked to avoid the area.
