The alert was raised shortly after 6:20 PM when authorities were informed about the presence of the suspected weapon. It was clarified that the individual did not make any threats towards fellow passengers.

A large-scale Garda response was initiated, including the deployment of several Armed Response Units from Dublin City. Following swift action, the suspect was apprehended at the scene and is currently being held at a Garda station in the Dublin region for further questioning.

The suspected firearm has been secured, and Gardaí have confirmed that a full technical examination will be conducted to verify its classification under Irish firearms legislation.

For safety precautions, Connolly Station was temporarily evacuated while authorities carried out a thorough security sweep of both the station and the train in question. Rail services have since resumed, but residual delays of up to 50 minutes are still being reported by Irish Rail.

In a statement, Gardaí reassured the public that there are no ongoing safety concerns and that Connolly Station has fully reopened.

Authorities have also addressed the spread of misinformation regarding the incident on social media platforms. The Garda spokesperson urged the public to verify information independently before sharing it online or via messaging apps.

Anyone with relevant information about the incident is encouraged to contact Store Garda Station at 01 666 8000, the Garda Confidential Line at 1800 666 111, or any Garda station.
