A HUNTINGDON 16-year-old has been arrested for suspicion of murder in relation to the death of a father of two who was killed after being beaten up. A murder investigation was launched in November after 51-year-old Duncan Tulloch of Wolff Close, Huntingdon died in Hinchingbrooke Hospital on November 3. Mr Tulloch admitted himself to hospital on October 8 where he told staff he was assaulted at around 9pm as he walked home. He received treatment and was discharged at 2.30am on October 9. He was readmitted to hospital on October 11 where his health deteriorated and he was moved to the critical care unit where he later died. A post mortem examination revealed Mr Tulloch had died from severe internal injuries "very likely" to be linked to injuries he sustained during an assault. He also had some broken ribs, scratches to his face and a black eye. Police believe his broken ribs were caused by a sustained force such as a kick. It is believed, Mr Tulloch was assaulted sometime around October 7 or 8 but the alleged assault was not reported to police until October 16. Speaking to the Hunts Post on Friday afternoon (January 9), a spokesman for Cambridgeshire police said: "A 16-year-old boy from Huntingdon has been arrested for suspicion of murder and has been bailed until January 28."
