An assistant commissioner of police, along with an inspector and a sub-inspector, quizzed Mr Sreedhar for about an hour.
"It is true that an ACP, with an inspector, had come to my office and sought some details. It is good that the SIT is leaving no stone unturned to probe the matter," said Mr Sreedhar.
"There is no likelihood of any Naxal involvement in Ms Lankesh's killing. It is the same gang, or rather, I should say the same boys, who had killed (Narendra) Dabholkar, (Govind) Pansare and (MM) Kalburgi. If they are not tracked down, there will be more killings in the near future," the "reformed" gangster added.
The Karnataka government had, on September 6, announced a 21-member SIT to investigate the killing of Gauri Lankesh, an incident which led to countrywide protests and condemnation across the political spectrum.
Ms Lankesh (55), known to be an anti-establishment voice was shot dead at close range by unknown assailants outside her residence on the night of September 5.
