Man arrested over Colin Hughes back garden killing
A 20-year-old man has been arrested on suspicion of the murder of a man who was killed in his back garden.
Colin Hughes, 42, was stabbed in the chest as he went to investigate a noise at the back door of his home in Old Swan, Liverpool, in September 2010.
Six other people have been arrested during the inquiry but no-one has been charged.
Detectives are continuing to question the latest suspect, from Broadgreen, following his arrest on Friday.
Mr Hughes had been playing cards with his fiancee Paula Greenwood when they heard the glass in the back door smash at about 0045 BST on 21 September.
Ms Greenwood went to call the police while Mr Hughes, a chef at a local pub, went to investigate. She later found him lying face down in the garden.
He was taken to hospital but died soon afterwards. A post-mortem examination found he died from a single stab wound.
