A man more than three time the drink-driver limit was arrested by police in Armagh on Wednesday afternoon.
Officers apprehended the man after being tipped off by a member of the public.
A PSNI spokesperson said: “Yesterday [Wednesday] afternoon we were contacted by a vigilant member of the public who informed us that they had observed a male getting into a vehicle in Armagh who was unsteady on his feet.
“Members of E section checked on the male and found that he was intoxicated and was taken to custody for a evidential breath test which came back at 110.
“Thank you to that member of public.
“If you suspect someone of drink driving, please phone 999 immediately. Don’t wait thinking someone else will do it.”
