New Delhi: Punjab police staying vigilant after the news of the breakout of Khalistan Liberation Force (KLF) chief Harminder Singh and other gangsters from the Nabha jail shot dead an innocent civilian near Patiala on Sunday. 
The incident allegedly occurred when the police purportedly tried to pull over a car for a routine check. However, when the car did not stop, the police, without any prior notice, riddled the car with bullets. 
A woman passenger inside the car was critically injured and was taken to hospital where she eventually succumbed to her injuries. 
Along with Harminder Singh Mintoo, the unidentified men also took along four other prisoners from the jail. Mintoo was arrested by Punjab police from Delhi’s IGI Airport in 2014. Four other gangsters who were freed by the ten armed men from Nabha jail are Gurpreet Singh,Vicky Gondra,Nitin Deol, Vikramjeet Singh Vicky. 
Mintoo was prosecuted by the court in ten terror-related cases which include the 2008 attack on Dera Sacha Sauda chief Gurmeet Ram Rahim Singh and the blast at Halwara Air Force station.
The Khalistan Liberation Force or KLF is an insurgent group, and is part of the Khalistan movement to create a Sikh homeland called Khalistan via armed struggle. The KLF appears to have been a loose association of scattered Khalistani groups.
