Janesville police are investigating what they describe as a methamphetamine lab operation at a downtown apartment. The building at 418 East Saint Lawrence Avenue is less than a block away from the Rock County courthouse.
Officers raided the apartment Sunday night, and found a large quantity of by-product, paraphernalia, and methamphetamine production related materials. The Janesville Police Department Street Crimes Unit has asked the State Division of Criminal Investigations to assist with the clean up. One person has been detained. Arrests are expected.
Investigators said they received information Sunday about a possible meth lab in the apartment.
