Westgate prison has already deployed cell phone blocking technology, according to Commissioner of Corrections Edward Lamb — but the equipment is currently offline for improvement.“We have for some time now had cellphone jamming equipment, with a good degree of success,” Lt Col Lamb told The Royal Gazette.The Commissioner’s remarks followed criticism in the Senate that Corrections needed to get tough on inmates using smuggled cell phones.Opposition Senator Marc Daniels called for “a more heavy handed approach” by prison staff, and questioned why the signal blocking equipment hadn’t been put to use.Cell phones are banned within the prison walls, Lt Col Lamb responded — with the exception of “a select few senior members of staff”.“Recently, we had the equipment inspected by engineers and currently we are seeking to upgrade its technological capabilities in order to keep up with advances in cell phone technology,” he added.Lt Col Lamb said prison authorities hoped to have the equipment “online as soon as possible.”
