A man in his 50s has been arrested following a security incident at Connolly Station in Dublin.
Shortly after 6.20pm, gardaí received reports of a man carrying a suspected firearm on a train arriving into the station.
It is understood the man was on the Sligo to Dublin service.
He was not alleged to have made any threats towards any passengers onboard.
Armed gardaí entered the station in central Dublin during the incident.
The station was evacuated and a security sweep of both the station and the train took place.
The man was arrested at the scene and has been detained under Section 30 of the Offences Against the State Act, 1939.
The suspected firearm was seized and a full technical examination will be conducted to determine its status under Irish legislation, gardaí said.
Connolly Station was closed during the incident but has since re-opened as there are no ongoing public safety issues.
Gardaí have appealed for anyone with information to contact Store Garda Station on 01 666 8000, the Garda Confidential Line on 1800 666 111 or any garda station.
They said it was “aware of commentary in circulation online in relation to this incident which contains misinformation, disinformation and fake news”.
“Once again, An Garda Síochána appeal to the public to independently verify any information that is shared on social media and/or sent through messaging sharing apps,” gardaí added.
A spokesperson for Irish Rail said all services to and from Connolly were suspended during the incident between 6.30pm and 7.15pm.
