A TATTOOED thug remained silent as he brutally tried to kill a man in his own home.

Christopher Simpson left Darren Martin with more than 20 injuries after repeatedly stabbing him at the flat in Glasgow's Castlemilk.

The 34-year-old carried out the unprovoked attack on August 21 last year after asking the victim for a glass of water.

Simpson pleaded guilty to an attempted murder charge at the High Court in Glasgow.

Prosecutor Colin Edward said Mr Martin had met Simpson before and allowed him into his flat.

The victim later refused to drink alcohol with Simpson and asked him to leave.

The thug then asked for some water before he left.

But, Mr Edward went on: "As Mr Martin stood at the sink, Simpson stabbed him twice.

"He then repeatedly stabbed him on the head, neck, body and arm.

"Mr Martin believed it was with scissors or a knife that he had hidden."

The terrified victim begged him to stop adding: "You are going to kill me."

But, Simpson ignored him, put the man in a headlock and carried on with the assault.

Mr Edward: "Simpson did not say a word throughout."

Simpson eventually stopped and the bleeding victim broke free.

The court heard he suffered a series of wounds including to his chest and abdomen.

Mr Martin had a punctured lung and also needed a blood transfusion.

He remains affected by his ordeal and has limited movement in his arm.

Mark Moir QC, defending, told the hearing: "This cannot to be said to be anything other than a serious and sustained attack."

Judge Sean Murphy QC remanded Simpson in custody and deferred sentencing until December 21.
