Garda watchdog Fiosrú has launched an investigation into the death of a man who was in the custody of Gardaí.

Aged in his 30s, the man was found unresponsive in a Dublin Garda station cell on Saturday and was later pronounced dead.

Gardaí and medical personnel attempted to revive him, though they were unable to do so.

A coroner was notified and the matter has now been referred to Fiosrú, the Garda watchdog, which attended the scene and launched the investigation.

Fiosrú confirmed in a statement that it received a referral from An Garda Síochána, as per Garda policy.

It said: ‘Fiosrú, Office of the Police Ombudsman, received a referral from An Garda Síochána on Saturday, 6 June 2026. The referral was made by a Garda Superintendent under section 203(1) of the Policing, Security and Community Safety Act 2024.

‘The referral was made following the death of an individual in the Dublin Metropolitan Region. Fiosrú’s on call team of investigators have attended the scene.

‘As the matter is now under investigation, pursuant to section 208(1)(b) of the Policing, Security and Community Safety Act 2024, Fiosrú cannot make any further comment.’
