14 jammers installed at Adiala jail
[Pak Daily Times] As many as 14 high-tech and powerful jammers have been installed inside and around the Central Jail Rawalpindi to tighten security arrangements therein.

The step has been taken to avert any untoward incident, like the ones that took place at the Bannu and Dera Ismail Khan
... the Pearl of Pashtunistan ...
jails.

These jammers have the potential to jam mobile phone and wireless phone communications within a distance of two kilometres around the prison.

The step to install jammers at all the prisons across Punjab is part of the government's additional security measures to snap the links of hardened prisoners with the outside world through mobile phones.
