Update 3.25pmA car fire which sparked a security alert in Northern Ireland was the result of a mechanical fault, police have confirmed.
British Army bomb disposal experts were called to examine the vehicle on the A2 between Belfast and Bangor amid claims from some public representatives it may have been a bomb.
In a statement, the Police Service of Northern Ireland (PSNI) said: "Police can confirm that a mechanical fault is believed to be the cause of a car fire on A2 between Belfast and Bangor."
The female driver of the car escaped injury in the incident, which happened at about 8.30am.
British Army technical officers spent several hours at the scene with a low-key police presence at the security cordon.
They left the area shortly after 1pm and the road was expected to re-open.
Update 12pm: British Army bomb disposal experts are examining a car that caught fire on a main road in Northern Ireland.
The female driver of the vehicle escaped injury in the incident, which happened around 8.30am on the A2 between Belfast and Bangor at around 8.30am on Tuesday.
The bomb disposal team is assisting police in their efforts to establish the cause of the blaze amid claims from some public representatives that it may have been an explosive device.
It is understood that the British Army experts have not yet confirmed whether that was the case.
Police sources said the woman who was driving the car is not a serving officer.
A Police Service of Northern Ireland (PSNI) spokesman said: "Police are currently working to establish the circumstances of how a car caught fire on the A2 between Belfast and Bangor this morning, Tuesday 6th March.
"The main A2 remains closed at this time while the investigation into the circumstances of the incident continue."
DUP policing spokesman Ian Paisley says it was a brutal act of attempted murder.
"I would echo the words of Martin McGuinness that if this is a nationalist attack or a republican attack that they are traitors, that they believe in nothing, that they are not serving any purpose and if it is an attack from any other source it is as dastardly and as horrible as it gets," said Mr Paisley.
