The campaign, which took place between July and September in 69 so-called 'priority' areas, saw more than 5,171 litres of alcohol confiscated from underage teenagers. A total of 3,721 actions were taken for drinking in public, and 500 dispersal orders were issued during the summer initiative.
In addition, almost 2,000 young people were referred to support services, and 1,829 parents were informed about their children's behaviour.
The campaign also included test purchasing of licensed premises. Of the 2,467 visits undertaken, 349 were failures.
Association of Convenience Stores chief executive James Lowman said the campaign showed the right approach to alcohol enforcement.
"We have learnt that the best way to tackle youth drinking is to target all aspects of the problem. This includes preventing underage sales, but also targeting the young people, breaking up gangs, confiscating alcohol and ensuring parents are reminded of their responsibilities."
