Boater Justin McDonald is serving eight weeks in prison after admitting possession of drugs and a CS gas canister at his narrowboat.

Police raided McDonald’s craft moored on the Kennet and Avon Canal in Devizes on Thursday November 26.

Their search turned up 104 grams of cannabis resin and herbal cannabis. They also found a CS gas canister, which counts as a firearm under the Firearms Act.

Detective Constable Mac McLennan said: “Mr McDonald had only recently been released from prison after serving 18 months for drugs offences. You are barred from possessing firearms for five years if you have served a jail term.

“We also found a crossbow with bolts, a loaded air pistol and a 12-inch knife, but as they were found at his home, he could not be charged with possession of those items.”

McDonald, 34, was arrested and interviewed by CID officers at Melksham.

He was remanded in custody and appeared before Salisbury magistrates charged with possession of: a Class B drug, a weapon for discharge of a noxious liquid, gas or other thing and a firearm. He pleaded guilty and was sentenced to eight weeks.
