An paramilitary trooper killed two of his senior officers and later shot himself dead in a bizarre shooting spree in Manipur, officials said on Saturday.
A defence spokesperson said Avdesh Sharma, a sergeant of the paramilitary Assam Rifles, on Friday picked up his service weapon and attacked a captain and a junior commissioned officer (JCO) at their base camp in Nongdam Kuki village, about 30 km from Imphal.
"This was a gruesome incident with the soldier suddenly going amok and firing indiscriminately with his service weapon and killing the captain and the JCO," an Assam Rifles commander said on conditions of anonymity.
Sharma later shot himself in the head before his colleagues could overpower him. He later died in hospital.
"We are not sure as to the immediate provocation for the attack," the commander said.
The Assam Rifles has ordered a probe into the incident in which Captain SJ Rai Choudhury and the JCO Ranjit Maimon died on the spot.
Another Assam Rifles commander said the sergeant went berserk after the deceased captain rejected his leave application.
"Probably the refusal to grant leave irked the sergeant," the commander said.
In September, an Assam Rifles trooper killed four of his colleagues and later shot himself dead in a similar incident in Manipur.
Stress and long hours of duty in remote locations far away from their homes are the reasons attributed for the increasing number of fratricidal killings in the Indian army and other security agencies.
The Assam Rifles is currently engaged in counter-insurgency operations in India's northeast.
