Minister Flanagan said "Private security staff occupy a position of trust, engaging in regular interactions with members of the public. It is therefore essential that this area is properly regulated in order to protect public safety and confidence.
“The Authority has made significant progress in regulating the private security industry since its establishment in 2005. I believe that confidence in the industry has greatly improved due to the manner in which the Authority carries out its functions, providing clients of private security service providers with assurance that the industry is working to the highest standards possible,” he said.
