Gardaí are investigating an incident where a man in his 40s, who was impersonating a member of An Garda Síochána, stopped an undercover garda drugs unit.
The man had fitted his car flashing blue lights on the front and rear of his Renault Megane.
His car was searched after he pulled up behind an unmarked car in Baldoyle.
Gardaí seized fake garda and fire officer badges along with a ‘fire officer on call’ sign.
The man was questioned and let go after his identity was established.
No arrests have been made yet.
