A Fullerton K-9 police officer pulled over a black Chevrolet Monte Carlo Tuesday night near Magnolia and Orangethorpe avenues.
Alfonso Cisneros, 28, of Pacoima, was driving the vehicle. The officer determined Cisneros was on probation for narcotics violations. The officer had his accompanying police dog search the car. The dog found 20 kilograms of cocaine in the suspect's trunk.
Cisneros was booked at the Fullerton City Jail on charges of transporting narcotics. He was held on $3 million bond and was scheduled to be arraigned Thursday.
