"Samuel is at the police station and is being questioned by senior officers," an officer at Muchipara police station, who did not wish to be identified, said.
Samuel reached the police station at around 12.30 pm and was being questioned by senior officers at Muchipara police station in the northern part of the metropolis.
Samuel had created a political furore after releasing vidoes of a sting operation allegedly conducted by him that showed people resembling senior Trinamool Congress leaders in West Bengal receiving money.
A summon was sent to Samuel by the police after an FIR in connection with the alleged extortion call to a former MP of Bihar was registered at Muchipara police station.
It was claimed in the FIR that an ex-MP of Bihar was asked to pay Rs five crore failing which a sting operation footage of him allegedly accepting bribe would be made public.
The extortion call was allegedly made from a hotel in Muchipara area of the city.
Police had raided the hotel room, seized a laptop and a mobile phone and claimed that the occupant was not in the room.
The laptop allegedly had a photo that resembled Samuel.
Samuel had earlier been asked to appear before the police by April 20, but he had then sought time claiming that travelling for him was prohibited as doctors had advised him complete bed rest for at least three months after a surgery.
