A man who was doused in petrol and set alight three nights ago has died in hospital.
33 year old Thomas O'Hare was at his home in Keady, Co Armagh with his 21 year old girlfriend when the attack occurred on Monday night.
His girlfriend, Lisa McClatchey who was also set alight, remains in a critical condition.
The PSNI say they are treating his death as murder.
They are investigating whether four men who remain in a Dublin hospital with severe burns, are linked to the attack.
