Officers executed a warrant on a canal boat, on the Kennet and Avon close to The Wharf automotive park in Devizes, on June 13, and reportedly found three hashish vegetation.
These vegetation had been seized and one man, in his 50s, was arrested on suspicion of rising hashish.
He has since been given a conditional warning and ordered to attend a drug consciousness course.
Sgt Chris Wickham revealed the warrant was carried out following intelligence supplied by a member of the general public.
A spokesperson for the power stated: “A person in his 50s was interviewed below warning for drug offences following a warrant on a canal boat close to Wharf automotive park, Devizes.
“Police searched the boat and seized three hashish vegetation on June 13.
“The person was arrested on suspicion of cultivating and producing hashish and was given a conditional warning with a medication consciousness course to attend.”
