Essentially owner of property catches a criminal, calls for help said help beats up the criminal, and he has now been sentenced to four years in prison. It seems that this is not the first time this has happened to him, so when he came across three intruders stealing his stuff took matters into his own hands, called a friend (who was not charged, for some reason) who smashed one of the intruders up, the owner then took him to hospital in a wheelchair where he spent several weeks and had surgery.
It is not clear whether previously or subsequent to the pummeling, but said intruder is now serving an unrelated sentence of four years for kidnap.
Seems odd that he would plead guilty, I would imagine most people would consider it fair enough, par for the course, occupational hazard of being a crook, and would struggle to convict.
