Karnan who had been awarded with six months imprisonment over contempt of court charges; had been hiding in lakefront resort in Kochi.
Meanwhile, the claims made by West Bengal Police Chief on Wednesday have raked up a fresh controversy as the Police Chief said, “The police team searching Karnan, knew about his hiding place in Coimbatore in Tamil Nadu for three days before moving in to arrest him”.
"We knew about his (Karnan's) whereabouts three days back. We were tracking phone calls of people close to him and we also have our own sources," Director General of Police Raj Kanojia told media.
Kanojia spoke at the Chennai airport before boarding a flight to Kolkatta.
According to him, this was a unique case he had handled in his entire service and "maybe no other police officer will be handling such a case in a long time to come".
"Tracking Karnan was difficult. It was a difficult case," Kanojia said.
Karnan, who was sentenced to six months imprisonment by the Supreme Court for contempt but was untraceable, was arrested near Coimbatore on Tuesday. Coimbatore is around 500 km from here.
Karnan was eluding arrest for more than a month.
