An investigation is under way after a man pretending to be a member of An Garda Síochána stopped an undercover garda drugs unit.

At around 3pm yesterday, the man, who is in his 40s, was driving a Renault Megane with blue lights flashing on the front and back.

He drove up behind a car in Baldoyle in north Co Dublin, which turned out to be an unmarked car from the divisional drugs unit.

His car was searched and fake garda and fire officer badges were discovered along with a large 'fire officer on call’ sign.

The man was questioned at the scene, the items were seized, and he was allowed go when his identity was established. 

The car has also been seized.

In a statement, Garda Headquarters said: "On Thursday 9th April 2020 at approximately 3pm gardaí observed a car utilising blue lights in the Baldoyle area.

"During a search of the car, a number of unofficial An Garda Síochána and Dublin Fire Brigade items were seized by Gardaí.

"No arrests have been made currently. Investigations are ongoing."
