Despite cell jammers and tightened security, criminals are using drones to bypass T&T’s prisons officials, smuggling cigarettes, phones and drugs into the system. Their warning follows Monday’s arrest of three men attempting to deliver contraband into the Maximum Security Prison (MSP) using a drone. Seepersad yesterday said while prisons have cell jammers, smugglers’ evolving tactics require stronger surveillance and laws restricting drone activity near facilities. Existing tools include Drone Geo-fencing, RF jammers, drone detection radar, net guns, and interceptor drones, he said. It is a matter of just deciding which one and putting it in place,” Seepersad said.
