# Cape Town Mayor Geordin Hill-Lewis has called for the introduction of cellphone signal-blocking technology at Pollsmoor prison. The mayor wrote to Correctional Services minister Pieter Groenewald this week expressing concern that criminal activities are being coordinated by cellphone from within Pollsmoor. Hill-Lewis says on a recent roads project inspection in Bishop Lavis, he was informed that the contractor had left the site due to extortion threats made by phone from an underworld figure inside Pollsmoor:
