BANGOR, Maine — Local police and investigators with the Maine Drug Enforcement Agency are investigating a suspected methamphetamine lab at a Hammond Street apartment.

Bangor police were called to 404 Hammond St. about 4 a.m. Wednesday by paramedics who had dealt with a medical call, according to Sgt. Tim Cotton, spokesman for the Police Department.

Officers called in the MDEA because they suspected the apartment was being used to manufacture small batches of the drug, Cotton said.

He said Wednesday that because the investigation began as a medical call, health care privacy laws prevented him from giving out more information.

No arrests had been made as of 5 p.m.

If investigators determine that it was a meth lab, it most likely would be the 21st of the year dismantled by the MDEA, according to Stephen McCausland, spokesman for the Maine State Police.
