Paul Cameron was found armed with a stick striking a gas pipe in a cupboard at property in Dalkeith, Midlothian, last August. He yelled at police: "I'll fight you all. I've cut the gas and I'll blow you up and set fire to you all."
Officers had arrived after Cameron had assaulted Karen Wilson with the martial arts stick.

Judge Lord Malcolm jailed him for four years and nine months at the High Court in Glasgow.
He also ordered that Cameron be supervised for a further six years on his release.
