The senior Garda officer in charge of the search for the two paintings stolen from Russborough House on Tuesday has said he is optimistic they will be found.
Assistant Commissioner Tony Hickey described the raid on the house as a "mad escapade".
Gardai suspect a gang from Dublin, possibly the south of the city, carried out the raid. The two vehicles they used were stolen in Crumlin and Knocklyon.
Yesterday, Mr Hickey appealed for assistance from anyone who was visiting Russborough House or in the area who knew anything about a silver-coloured car, possibly a Nissan Almera or Primera, parked in the car park there.
Two Garda patrol cars were nearby when the paintings were taken, setting off an alarm at Naas Garda station. Gardai arrived within minutes.
The gang tried to set fire to the jeep but the first gardai to arrive doused the flames. The three robbers drove off in a Volkswagen Golf which they burned a short distance away. Carrying the paintings they then tried to hijack a car, firing a shot from a handgun as they did so. No shell case, spent bullet or a strike mark has been found.
It is also thought the gang had a third car but lost contact with it in their confusion after the robbery.
The man whose car they tried to hijack did not see what happened after the gang ran off. When the gardai arrived and were speaking to him they saw the smoke rising from the Golf in a nearby car-park.
As the gang ran from the burning Golf they threw spikes of twisted and welded nails on to the road.
One of the stolen paintings, Portrait of Madame Bacelli by Gainsborough, valued at £2 million, was stolen from the house in 1974 and in 1986.
