Gardaí in Dublin conducted over 500 checkpoints in the capital and its surrounding counties over the weekend.
The move, part of Operation Fanacht, came in the wake of the Government's decision to limit travel in and out of Dublin.
Meanwhile, the gardaí have reported the vast majority of pubs have complied with public health regulations.
As part of Operation Navigation, An Garda Síochána conducted thousands of checks on licensed premises. Since July 3, there have been 232 potential breaches.
Fifteen potential breaches of the public health guidelines were reported on the week of Monday, September 14. Files for each case are being prepared for the DPP.
Deputy Commissioner, John Twomey said, "Some licensed premises are risking the health of their employees, customers and local communities.
"We are at a critical point in tackling the spread of COVID-19 and everyone must take personal responsibility to avoid situations that are a risk to themselves, their family and their friends.”
