A suspected arson attack on a speed camera van has been condemned by the Garda commissioner.
Commissioner Martin Callinan said GoSafe, which operates the mobile cameras, was helping gardai reduce the number of deaths and serious injuries on Irish roads.
Gardai have made a fresh appeal for information after a Citroen Relay van, registration 11 KK 491, was set alight on the old N11 road at 7.30pm on Sunday.
The operator escaped unharmed from the van, parked half a mile south of Arklow on the Gorey Road.
Commissioner Callinan said on Monday: "GoSafe are working on a daily basis to assist An Garda Siochana in reducing speed-related collisions and stop loss of life and serious injury on our roads.
"Their work at the side of the country's roads helps to save many in our communities from the tragedy and pain of the loss of family and friends in road collisions.
"It is so wrong that this vital work directed at making our community safer for everyone should be the subject of such mindless attack.
"We are fortunate that no-one was injured in last night's incident and I want to condemn it in the strongest terms."
There have been several arson attacks on mobile speed cameras since they were rolled out across the country in November.
Operated by trained GoSafe personnel, they provide 6,000 enforcement hours and 1,475 survey hours per month nationwide.
