An investigation is underway to see if any serving Gardaí are tipping off a criminal gang.
It’s after a retired senior Garda was arrested on Wednesday as part of an inquiry into the drugs trade in Dublin.
A number of searches have been carried out and drugs and cash have been seized.
Crime Editor with the Irish Times, Conor Lally, says inquiries are ongoing:
"If you get tip offs about what kind of plans An Garda Síochána has, particularly if it's plan specific to your gang's operations, that can really help you. And it's always a massive fear within An Garda Síochána that information will be passed on. This is a very large investigation, very serious inquiry, and it will take some time, but as I stress, there's no findings any wrongdoing have been arrived out at the moment."
