After a woman on probation for drug violations failed a drug test May 5, Adult Probation and Parole agents searched her boyfriend's residence, 2301 S. Lake St. (about 740 East), and found chemicals and equipment used in the production of methamphetamine, according to charges filed in 3rd District Court Thursday.An agent also "discovered a trap door in the floor of the living room that led to a basement room containing what he suspected to be an operational clandestine laboratory for the production of methamphetamine," the charges state.

Finished methamphetamine was also found at the residence and inside a truck and a car parked outside the house.

The woman, 28, and her boyfriend, 36, have been charged with operation of a clandestine lab, a first-degree felony, and unlawful possession of a controlled substance, a second-degree felony. The woman is being held at the Salt Lake County jail in lieu of $15,000 bail; the man is being held in lieu of $60,000 bail.
