A man has been arrested after 20 cannabis plants were found in a van.
Officers had spotted the van as it tried to avoid their patrol car in Walton, Liverpool, between 01:30 and 02:45 on Thursday, Merseyside Police said.
The driver of the van, a 32-year-old man from Liverpool, left the vehicle and was later detained on Olney Street, a force representative said.
He was arrested on suspicion of being concerned in the production of a controlled Class B drug and was taken to a police station. He was later released under investigation.
