Kevin Kearney murder: Man arrested in north Belfast 25 November 2013 Last updated at 11:42 Detectives investigating the murder of man who was shot dead by dissident republicans in north Belfast last month have arrested a man. The body of 46-year-old Kevin Kearney was found in a lake in Alexandra Park, off Antrim Road, on 9 October. The father-of-four, from Dunmore Road in north Belfast, had gone missing the previous day while walking his dog. The arrested man, who is 33, was detained in the north of the city on Monday morning. Mr Kearney went missing on 8 October, shortly after he left his daughter off at school, returned home and took his dogs for a walk in Alexandra Park. Shortly after the killing, the Irish News reported that it received a statement from a dissident republican group calling itself "the IRA" that claimed it had killed Mr Kearney. In July 2012, a new paramilitary group styling itself "the IRA" is believed to have been formed from an amalgamation of previously disparate dissident republican organisations.
