Two central agencies - the CBI and the ED - questioned Trinamool Congress MP Mukul Roy and West Bengal Transport Minister Suvendu Adhikari respectively in connection with the Narada sting probe, officials said on Monday.
"Adhikari was summoned earlier as a part of Narada sting probe but he appeared before our investigation team today (Monday). He was interrogated," a Enforcement Directorate (ED) official said.
Roy was also summoned by the Central Bureau of Investigation (CBI) to appear before the agency for questioning.
"He appeared today and was questioned," a CBI official said.
Adhikari and Roy were among a dozen Trinamool leaders allegedly caught on video tape while receiving money in exchange for a promise to dole out favours to a fictitious company. The clipping was uploaded on the Narada news portal in March last year ahead of the assembly elections in West Bengal.
Both the agencies, which are probing the case, have already interrogated many of the accused party leaders.
