A driver in Co Cork was arrested twice on suspicion of drink driving over a six-hour period, gardaí say.
He was one of five people arrested on suspicion of driving under in the influence in Mallow between the 17th and 18th December.
Four of the arrests were made for suspected drink driving, while one was for drug driving.
A number of checkpoints were carried out over a 24-hour period as part of local gardaí's policing plan for Christmas.
Inspector Joe O Connor, the head of the Roads Policing Unit in North Cork, said: "Our Christmas Road Safety Campaign will run until 5th January, 2021 and will primarily focus on detecting those who drive having consumed alcohol or drugs.
"Gardaí will continue to enforce all road traffic legislation and try to reduce the risk of collisions on the roads. We will focus on driving under the influence, speeding, not wearing a seatbelt and holding a mobile phone whilst driving.
"Never get behind the wheel if you are under the influence of drink or drugs.”
Files are now prepared for in the local district officer in relation to all five of the incidents.
