"Officers found the van unattended a short time later in the street and discovered drugs inside.
"Another vehicle, a VW Polo, was also seized and taken to a vehicle recovery yard. That car was searched today and more cannabis was found in the boot."
Meanwhile, a driver was arrested after being found with cannabis in the back of a car on the M54 overnight.
