DISCONNECT THEM PLEASE: Cellphone signals must be blocked at Pollsmoor Prison, says Cape Town mayor Geordin Hill-LewisCAPE Town mayor Geordin Hill-Lewis has called for cellphone signal-blocking technology to be piloted at Pollsmoor Prison, warning that inmates are using mobile phones to run criminal networks from behind bars. “The City has received various reports that crime and extortion activity is being coordinated by phone from within Pollsmoor," Hill-Lewis said. “This shows we must do more than just jail criminals, we have to prevent their ability to coordinate crime from within prisons. “I have written to [Groenewald] to offer the City’s full support to pilot sophisticated signal-blocking tech at Pollsmoor. “We have to flip the switch on cellphones in prisons, and we welcome the minister’s public commitments to cracking down on this.”
