Gardaí have arrested a man in Dundalk, Co Louth, after he was spotted carrying a knife in public.

The incident took place at a car park at about 9.30pm on Monday.

Uniformed gardaí, backed by members of the Armed Support Unit, engaged with the man and directed him to drop the knife.

When he refused, they fired one shot from a “40mm less-lethal force option” and he was disarmed.

The man, who is in his 30s, was arrested at the scene and taken to Dundalk Garda station.

He is due to appear before Drogheda District Court on Tuesday.

A Garda spokesman said he received appropriate medical treatment in custody.

The Garda said the discharge of a less-lethal device has been notified to the Office of the Police Ombudsman (Fiosrú).
