MUSSOORIE: An Indo-Tibetan Border Police ( ITBP ) jawan on Friday went on a shooting spree killing his officer and injuring another personnel inside the prestigious IAS academy here, a day after he was punished by the senior.

The misery for the force did not stop here as the accused constable, Chandra Shekar, ran away with an assault rifle and 70 rounds of bullets from Lal Bahadur Shastri National Academy of Administration ( LBSNAA ).

The ITBP force guards the premier institute located on this hill station in Uttarakhand.

The story of the gory incident is said to have begun yesterday when sub inspector Surendra sentenced Shekar for a day's punishment over disciplinary issue.

Apparently peeved over the decision of his superior, the constable opened fire with a light machine gun (LMG) killing Surendra and injuring constable Mohammed Alam at around 6 PM.

ITBP Director General Krishna Chaudhary told PTI that he has ordered a court of inquiry into the incident and directed for the "immediate" replacement of the unit from the task.

Officials said the incident was reported around evening when it is suspected that an altercation broke out between the two men and subsequently Shekhar grabbed an LMG and pumped at least three bullets into the SI and also shot at few others standing nearby.

They said the firing of the bullets led to some panic inside the Academy, however, senior officials soon announced that the situation was under control.

Senior ITBP commanders of the force and those from local police and administration rushed from state capital Dehradun to the Academy.

Officials said a search has been launched to nab the accused who joined the force in 2012.

The LBSNAA was established here in 1959. ITBP has close to 80 troops drawn from their 34th battalion posted here.
