A 55-year-old man has admitted to the murder of a pensioner who was stabbed after going to the aid of his neighbour - a convicted paedophile - during a robbery.
Ian McLoughlin appeared at the Old Bailey today where he admitted killing Graham Buck in Little Gaddesden, Hertfordshire, in July.
Mr Buck, 66, suffered fatal stab wounds when he responded to cries from the home of 86-year-old Francis Cory-Wright in the village near Berkhamsted.
