The Enforcement Directorate (ED) on Thursday summoned Narada channel's Mathew Samuel on May 18 in the Narada sting operation case.
The Central Bureau of Investigation (CBI) which is investing charges of corruption, has already questioned Samuel.
The Enforcement Directorate filed its case under the Prevention of Money Laundering Act (PMLA) after the CBI filed its case.
The sting operation pertains to the secret filming of the Trinamool Congress (TMC) leaders and the IPS officer while they allegedly accepted money from the representatives of a fictitious company for extending favours to it.
The TMC leaders against whom the CBI has registered the FIR, now also booked by the Enforcement Directorate, include Rajya Sabha MP Mukul Roy, Lok Sabha MPs--Saugata Roy, Aparupa Poddar, Sultan Ahmed, Prasun Banerjee and Kakoli Ghosh Dastidar.
West Bengal ministers including Urban Development Minister Firhad Hakim, Transport Minister Suvendu Adhikari, Environment Minister Sovan Chatterjee, Panchayati Raj and Rural Development Minister Subrata Mukherjee have also been named in the FIR.
Former Minister Madan Mitra, MLA Iqbal Ahmed and IPS officer Saiyaad Mustafa Hussain Mirza have also been made accused in the case.
