A 44-year-old man who works in the facilities department of the National Museum of Ireland has been charged with allegedly hiding an explosive device at Collins Barracks in Dublin, one of the museum’s main campuses.
Simon O Donnabhain, who is employed directly at the institution, was well known among circles supporting dissident republican figures before his arrest. He had regularly shown up at protests in Dublin backing individuals jailed on both sides of the border in connection with dissident activity.
The case has raised serious questions about security vetting procedures at one of the country’s most visited cultural institutions. Collins Barracks, the former military complex on the north quays of the Liffey, now houses a major branch of the National Museum and attracts thousands of visitors and school groups throughout the year.
Garda investigators are understood to have moved quickly once the device was discovered on the grounds. The fact that O Donnabhain worked in the facilities department meant he would have had regular and largely unrestricted access to various parts of the site, including areas not open to the general public.
His attendance at pro-dissident protests had apparently been noted before his arrest, though it is not yet clear whether that activity had ever triggered any formal review of his employment or access rights at the museum. Those protests, held at various locations around Dublin, were typically organised in solidarity with republican prisoners held in Portlaoise and in jails in the North.
The charges against him are being taken extremely seriously by authorities given the location involved. Planting an explosive device at a national cultural institution in the heart of the capital would represent a significant escalation in dissident activity, and gardai are treating the investigation as a priority.
O Donnabhain appeared before the courts following his arrest. The case is expected to proceed through the serious crimes process given the nature of the charges involved.
The National Museum of Ireland has not made any detailed public comment on the case, though the institution is expected to carry out an internal review of its security and vetting arrangements in the wake of the arrest. Questions will inevitably be asked about how someone with a visible profile at dissident-linked events came to hold a position with that level of site access.
Security at heritage and cultural sites across Ireland has come under increased scrutiny in recent years, with authorities acknowledging that soft targets require more attention than they have historically received. The Collins Barracks campus, given its history as a military installation, holds particular symbolic weight and has long been considered a sensitive location.
No injuries were reported in connection with the incident, and the device was made safe by specialist units. Gardai have not confirmed whether they are looking at any additional suspects in connection with the find.
The case is continuing.
