District officials in Pathankot Tuesday reportedly sounded an alert in villages around the Indo-Pak border after the Border Security Force (BSF) soldiers informed the police about the presence of at least three suspects on the Pakistani side. 

Patrolling has been increased along the border in order to prevent any infiltration attempt. Dhinda Forward Post of BSF is located in the Bamial area near Zero Line of the border, where suspects have been seen, Press Trust of India reported.

"An alert has been sounded in and around villages located near Indo-Pak border and night patrolling by security personnel has been stepped up in the wake of information with regard to suspects shared by BSF personnel," a Pathankot district police official said.

"Three to five suspects were spotted by our surveillance equipments in Pakistan side near the Zero Line and thereafter Pathankot police authorities have been informed in this regard," a BSF official said.

Apart from increasing patrolling, the district police has set up check-posts across the area near the border, and places surrounding village panchayat Narot Jaimal Singh in Punjab's Gurdaspur district has been sealed.

The incident comes even as Pakistan is investigating the Jan. 2 attack on the Indian Air Force base in Pathankot on the basis of the evidence provided by India. The militants who attacked the airbase were suspected to have entered India from the Pakistani side of the border. At least seven security personnel and all the six militants were killed in the encounter that lasted about three days.
