STERLING HEIGHTS, Mich. (AP) — Police in suburban Detroit seized 200 pounds of marijuana during a traffic stop.

Police in Sterling Heights, about 15 miles north of Detroit, say four men were taken into custody after the prepackaged marijuana was discovered during the stop. Police were investigating what they said is a source of “high potency marijuana” from California.

Three men were in the vehicle and the fourth person was arrested after search warrants were executed at other locations. Police said they also seized money and a vehicle in addition to the drugs.
