Liam Michael Christie smuggled cannabis into Magilligan 28 May 2013 Last updated at 14:34 A man who pleaded guilty to smuggling 40g of cannabis resin into Magilligan Prison and then passing the drugs to a prisoner has been jailed for six months at Londonderry Crown Court. Liam Michael Christie, 34, committed the offences at the prisoners visitor centre on 27 July 2011. He admitted supplying and possessing the cannabis resin. He also admitted possessing 86 Diazepam tablets found in his flat after his arrest for the prison offences. A prosecution barrister said that Christie, from Alliance Avenue in Belfast, who had 26 previous convictions, called at the prison with another man to visit a sentenced prisoner. Prison staff noticed both visitors acting nervously and Christie shaking hands with the prisoner twice. As the prisoner walked back to the prison wing after the visit he was seen throwing away a package containing the drugs. Christie attempted to quickly exit the visitor centre, but was detained by the prison staff. Judge Philip Babington said the six month jail sentence would be consecutive to a 10 month sentence Christie is currently serving for conspiracy to rob.
