Violent paranoid schizophrenic Hakan Yagiz stabbed disabled charity worker Gill Montgomery, 53, during a bungled burglary in 1995. After the killing - committed for 100 to feed his drug habit - police raided his Southwater Road flat where they discovered blood-stained clothes and a cache of knives including the murder weapon. Yesterday (Thursday) he was detained indefinitely after a judge heard how he kicked and punched fellow inmate Wayne Kingdom at Lewes Prison, breaking his jaw and four of his teeth after a row, on December 12. Yagiz was on remand for assault and battery on his mother and sister at the time. In interview, Yagiz said he believed Mr Kingdom had jumped on to his bed to annoy him so he "stuck him one to teach him a lesson". He told police: "You know what I mean, just disrespecting. And then he's disrespecting again and then he wants a bit more. "I said, 'Shut your teeth' and kicked him in the mouth. He started crying and yelping and all that. "He said, 'I didn't mean it'." Yagiz admitted causing grievous bodily harm. Sentencing him, Judge David Rennie said: "I am satisfied that it is appropriate for you to be detained without limitation under the dual diagnosis of mental illness and psychiatric disorder. "You pose a serious risk of harm and it is necessary for the protection of the public." After murdering Miss Montgomery in 1995, 34-year-old Yagiz, who has dual nationality, fled to Turkey where he joined the Army but was tracked down by British detectives. Authorities in Turkey refused to extradite him, and tried him under their own penal code on the basis of witness statements which were sworn in front of a British magistrate. He is thought to have become the first Turkish national convicted and sentenced in his own country for a crime in Britain. A court in Istanbul spared him the death penalty but ordered that he serve 36 years hard labour in May 1999 after being found guilty of killing Mrs Montgomery in order to commit robbery. But he was freed under a government pardon and conditional release of prisoners in the Tekirdag province, and he returned to his parents' home in Seven Acre Close, Hastings. The Crown Prosecution Service said it could do nothing about the case as it had been handed over to the Turks and Yagiz could not be tried twice for the same crime.
