A trainee sub inspector, Amarjeet Singh, shot dead his senior colleage Kailash Yadav, 41, on Thursday. Yadav had been presented with a gallantry award for his role in the investigation of several blast cases including the Sarojini Nagar blast. The incident took place inside the Nihal Vihar police station in west Delhi.
V Renganathan, additional commissioner of police (west) said, Yadav, who had been posted at the Nihal Vihar police station after being transferred from the Special Cell three months ago, was shot twice in the chest by Singh, around 5.15pm.
"There wasn't even any argument between the two. Yadav was doing some paperwork in his room when Singh went inside and shot him twice," said a senior police officer.
Yadav, who is survived by his wife and two children, was rushed to the Action Balaji Hospital in Paschim Vihar, where he was declared dead.
"We haven't told his wife yet. Our parents are coming from Jhansi," said his brother inconsolable Harish Yadav.
Yadav had received the Gallantry Award in 2008. He had also helped crack many cases related to the underworld.
"Singh joined the force in 2009. Last month, he had consulted a psychiatrist at the Deen Dayal Upadhyay (DDU) hospital. I think he is mentally unstable, but this could also be a preplanned murder. We can't overlook any angle," said a senior police officer, a colleague of Yadav's. Singh has been arrested and is being questioned.
