"He was interrogated today (Thursday) as part of the Narada sting probe," the ED official said.
Ahmed was 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.
His brother and party MLA Iqbal Ahmed was also quizzed by the agency in connection with the case on Wednesday.
Both Trinamool leaders were also questioned by the Central Bureau of Investigation in the case.
