All Luas trams are operating as normal following an earlier evacuation amid reports of the discovery of a suspicious device.
Passengers on all trams on the Red and Green lines were ordered to get off just after 6pm and in some cases to move away from the platforms while security personnel searched empty trams.
A statement from Luas just after 7.20pm said that all services have resumed.
:“Passengers, please be advised that the Red and Green Lines have now reopened. Please expect delays while we regulate services. Luas tickets remain valid on Dublin Bus. We will update passengers in due course. We apologise for any inconvenience caused.”

A spokesperson for An Garda Síochána said: “Earlier this evening, Transdev Dublin Light Rail, LUAS operators reported to An Garda Síochána that they had received a phone call in relation to a potential threat to the tram service. All Luas trams were stopped at the nearest Luas stop and passengers were evacuated in the interests of public safety.
An Garda Síochána worked with Luas staff to search all operational trams. Nothing of concern was found and the Luas has returned to full operation. An Garda Síochána has no further comment at this time.
