RTÉ News has learned that the man injured in a bomb attack in Navan, Co Meath, this morning was a former garda informant.

Paddy Dixon, 48, was injured after he opened the door of his home in the Beech Grove estate and a booby trap bomb exploded.

Gardaí were called to the incident at 8am and the area is currently sealed off while a technical examination gets under way.

Mr Dixon received minor injuries and is now under armed guard in Our Lady Of Lourdes Hospital.

It is understood Mr Dixon was a garda informant for former Detective Sergeant John White - who was sacked from the force following the publication of the Morris Tribunal report.

The tribunal found that Mr White had planted a shotgun at a travellers' halting site in Burnfoot, Co Donegal.

Mr White was subsequently acquitted of criminal charges.

Paddy Dixon was a car thief from Blanchardstown who gave information to John White about stolen cars which were subsequently used to transport Real IRA bombs.

Mr Dixon was under garda protection and was never in the Witness Protection Programme.

He is believed to have been living quite openly in Navan for the last number of years.
