Kolkata, Jul 13 (IANS): Indian Police Service (IPS) officer S.M.H. Meerza, summoned for questioning in connection with the Narada sting probe, appeared at the city police headquarters here on Wednesday.

The sting conducted by Narada News accused several high profile leaders of West Bengal's ruling Trinamool Congress and also Meerza, a former superintendent of police of Burdwan, of taking bribe.

Chief Minister and Trinamool supremo Mamata Banerjee had in June ordered a probe headed by city police commissioner to find if there was a "conspiracy" behind the sting.

The city police has also summoned Narada News editor-in-chief Mathew Samuel, who had conducted the sting.

The journalist who has been booked for several offences, including defamation and forgery, is yet to appear for questioning and has twice written to the police seeking withdrawal of the summons, as he contended the matter was pending before the Calcutta High Court.

Multiple litigations seeking an independent probe into the sting are pending before the court which has ordered a forensic test of the footage and devices used for the sting.
