Members of the Maine Drug Enforcement Agency’s clandestine drug lab team were at the scene of a suspected methamphetamine manufacturing operation at a house on Gilbert Farm Road in Bar Harbor on Wednesday, Maine State Police said.

Police took three people into custody, according to a news release from Stephen McCausland, spokesman for the Maine Department of Public Safety.

The lab is the third that agents have raided so far this year.

Last year, drug agents raided 28 labs and nine sites where byproducts of the drug manufacturing had been disposed of.

Police did not release the names of the people who had been taken into custody.
