A Haverfordwest man was found with "an ugly" weapon the likes of which an experienced judge had never seen before.

Rhys Davies, 21, had a knuckleduster with metal probes attached that could deliver an electric shock to a victim.

Davies also had a can of CS gas in a drawer at his home in Glebe House, Winch Lane.

Swansea crown court heard how Davies had been arrested on September 15 for a different matter and police told him that officers would now search his home.

Ashanti-Jade Walton, prosecuting, said the electric shock from the knuckleduster could have stunned a victim in addition to the damage caused by the knuckleduster itself.

Officers also found a small amount of cannabis and two cannabis plants under cultivation.

Davies admitted two offences of possessing weapons capable of emitting noxious substances and possessing and cultivating cannabis.

Judge Paul Thomas said, "I have never seen a knuckleduster like that before. It is an ugly weapon and there is not a conceivable, legitimate reason for having it."

Barrister Carina Hughes, representing Davies, said he had not appreciated that simply possessing the weapons were offences.

"That would not be of much comfort to anyone confronted by that knuckleduster," replied the judge.

Miss Hughes said both weapons had been given to Davies by friends.

Judge Thomas said he was sceptical about that.

"What did he think they were for? Ignorance of the law is no defence," he added.

Judge Thomas said he accepted Davies had not taken the weapons out of his home.

He warned Davies he could have been jailed for 10 years and told him that if he ever came back to court the ending would not be a happy one for him.

Davies was jailed for 30 weeks, suspended for 18 months.

He was also ordered to complete 25 days of a rehabilitation activity and 150 hours of unpaid work.
