A Central Industrial Security Force (CISF) head constable allegedly shot dead three of his colleagues working with the Kalpakkam atomic power plant in Tamil Nadu on Wednesday.
Head constable Vijay Prathap Singh allegedly opened fire from a 9mm carbine, killing assistant sub-inspector Ganesan and head constables Subburaj and Mohansingh at the CISF barracks in Kalpakkam township, which is some 10 km south from the nuclear complex, said government officials.
"Three CISF personnel have been killed. The incident happened around 5.30am. We are enquiring into how the incident happened," C Vijaya Kumar, Kancheepuram Superintendent of Police, told PTI.
Assistant sub-inspector Prathap Singh and head constable Govardhan Singh are being being treated at a hospital for injuries, police said. Prathap Singh, the official blamed for the firing, is under arrest.
Asked whether operations at the nuclear complex was affected due to the incident, Madras Atomic Power Station Director T J Koteeswaran told PTI, "The incident happened some 10 km away in the township and so operations were not affected. I am awaiting more information on the incident." Early media reports had said the firing took place in the power plant.
CISF, which has about 1.45-lakh personnel in its ranks, is tasked with the security of the 59 civilian airports in the country and also has the responsibility to secure installations in the nuclear and aerospace domain.
