A TERRORIST gang that murdered a policeman in Northern Ireland has been linked to nine other dissident republican crimes.

Making a fresh bid for public help to catch the killers of Constable Ronan Kerr, the officer leading the investigation said he believed members of the group were also responsible for another murder bid on police, other dissident attacks, armed robberies and a major arms find.

PSNI detective superintendent Raymond Murray also said some of the gang had been affiliated with other dissident factions.

No-one has yet been charged with the murder.

Mr Kerr, 25, died when a bomb detonated under his car in Omagh, Co Tyrone, last April. A group claiming it was made up of former members of the Provisional IRA claimed responsibility.
