LEWISVILLE (KRLD) - With the help of a K-9 officer, Lewisville police make a huge drug bust.
It was Sunday afternoon when Lewisville police received an anonymous tip about a suspicious tractor-trailer.
Officer Pat Robey brought along his K-9 partner Stryker to do what the department calls a "free air sniff" on the trailer.
Lewisville police say it's one of the largest drug busts in the history of the city.
