Portugal is installing signal jamming technology at the Vale de Judeus prison following a September 2024 escape involving five inmates. The equipment, designed to disrupt mobile phone and drone communications, experienced delays in delivery due to issues linked to Israel. Authorities hope the blockers will prevent future illicit communication that could aid further escape attempts or criminal activity within the prison walls. The installation aims to enhance security measures at the facility, which was compromised during the recent breakout. Details regarding the specific nature of the Israeli-related delays have not been disclosed. This move reflects a broader concern about the use of technology by prisoners and the need for robust counter-measures. The prison administration anticipates the system will be fully operational shortly.
