One man is in custody as RCMP and Truro police dismantle a methamphetamine lab in Salmon River.

They're inside a mobile home on Matheson Drive. The road is closed to traffic as they conduct their investigation.

They said right now, safety is their main concern.

CBC reporter Jill Coubrough said the scene reminds her of a movie.

"About half a dozen investigators dressed in HAZMAT suits entered the property just minutes ago. A robot entered first to clear the trailer and measure the air quality because it is potentially toxic," she said.

A man was arrested Tuesday night, but no details are known.

The RCMP Synthetic Drug Section and RCMP Clandestine Laboratory and Enforcement Team continue to investigate.
