Allan Turnbull, 29, was charged with firearms offences after police raided his house and discovered a stun gun disguised as a torch.

His solicitor, Ian Houston, told Dundee Sheriff Court that he did not know it was a stun gun until he tested it on himself.

Mr Houston told the court: “He used it primarily as a torch but does admit it was advertised as a torch with a self defence mechanism — he did not realise what that was. It was only when he got it that he realised and then tested it on himself and did not use it again.”

Mr Turnbull admitted the offence and was jailed for five years.
