Around 11:30 p.m. on Wednesday, officers spotted a vehicle driving without its headlights on near the intersection of Harrison and Holmes avenues.
After pulling the vehicle over, police questioned the male driver and female passenger.
According to police, the female identified herself as a juvenile and gave a false name. When she was subsequently identified as 35-year-old Amanda Housel of Butte, police arrested her on a misdemeanor charge of obstructing a peace officer.
After reportedly identifying the driver of the vehicle, Jack Azure Sr., 61, of Butte, as being in violation of parole, police called a tow truck to move the vehicle.
According to police, the tow truck operator identified a small baggie containing a substance that appeared to be methamphetamine as well as a bag containing syringes and foil with a substance also believed to be methamphetamine.
Azure was booked for possession of dangerous drugs and possession of drug paraphernalia, among other charges.
The substance believed to be methamphetamine has been sent to the state crime lab for testing.
