The alert was issued to Khyber-Pakhtunkhwa (KP) provincial government yesterday by Inspector General of Prisons (IG).
"The militants may storm jails to free high-profile prisoners before execution," the letter by the Inspector General warns, adding that while some militants are kept in Haripur and Peshawar jails, many high-profile militants were lodged in jails of Kohat, Timergara, Bannu, Dera Ismail Khan and Manshera.
The IG further requested the KP government to issue a security alert to law enforcement agencies to ensure fool- proof security arrangements of all jails in the province, the Dawn reported.
In April 2012, over 100 militants had stormed into the central prison of Bannu and freed 384 prisoners.
Earlier yesterday, Pakistan lifted a self-imposed moratorium on death penalty in terror related cases, a day after ruthless Taliban militants massacred at least 148 people, mostly children, in an army-run school in Peshawar, the administrative capital of the KP province.
The outlawed Tehreek-i-Taliban Pakistan (TTP) has claimed responsibility for the attack, saying, it was in revenge for a ferocious army offensive - Zarb-e-Azb - that has been underway in the tribal areas since the summer and has left an estimated 1,200 militants dead and tens of thousands of people displaced.
