Around 20 underage drinkers were caught boozing by police in a pub in the Newry area on Saturday night.
PSNI were calling in on licended premises as part of their Operation Noomin, which has seen them checking door staff across the country to make sure accreditation is in order.
Police confirmed that around 20 young people were removed from the pub in question, with four of them carrying “rather dodgy” fake IDs.
A spokesperson for PSNI Newry and Mourne said: “The owner of the premises was cautioned for allowing minors on licensed premises and the parents of the young people will be spoken to in due course.
“Please make sure you know where your kids are and who they are with.”
Speaking about the operation, Detective Superintendent Bobby Singleton said: “The joint operation will work towards keeping people safe by ensuring only legitimate licensed door staff are employed at venues where they can work in partnership and contribute to protecting the public.”
He also mentioned that there was be a particular focus on this weekend due to A Level results being released last week, and a focus on next weekend, with GCSE results due to be released on Thursday.
