A French farmer has been given a one-month suspended jail sentence and fined 500 euros (£428) for feeding his ducks marijuana to rid them of worms.

Police arrested Michel Rouyer after they discovered 12 cannabis plants and about 5kg (11lb) of the drug during a visit to his home after a theft.

Mr Rouyer said there was "no better worming substance" for ducks and that his flock was in excellent health.

A police spokesman said it was the first time they had heard such a claim.
