Orissa's police chief on Tuesday virtually ruled out any Maoist link in the killing of Deputy Inspector General of Police Jaswinder Singh, saying it could have been due to "accidental firing" by one of his security officers.
"It could have been due to accidental firing by one of the personal security officers (PSO)," state police chief Amarananda Patnaik said.
Jaswinder Singh was shot dead on Monday while travelling in plain clothes through Raigada district in a private vehicle.
Earlier, police had suspected Maoists to be behind the killing.
"However we did not find any evidence of Maoists' involvement during the combing operations launched soon after the shooting. From the statement of the PSOs, we suspect it could be accidental firing," said Patnaik.
Singh, who was in charge of the southern western range and was posted at Sunabeda in Koraput district, was going to Raigada when some unidentified people stopped his Bolero car near Laxmipur village, 15 km from Raigada town, around noon. The men asked him for money. Singh reportedly refused and returned to the vehicle when someone shot him from behind. He got a bullet injury in the head.
A bleeding Singh was taken to the government hospital at Raigada where doctors declared him dead.
The matter is under investigation and no arrests have been made so far, the police chief said.
Singh's body would be taken to his home state of Punjab via Visakhapatnam and Delhi on Tuesday.
