Purkayastha had earlier told a Delhi court that "not a penny has come from China".
The FIR in the case stated that the news portal allegedly received large amounts of funds that came from China to "disrupt the sovereignty of India" and cause disaffection against the country. It further alleged that Purkayastha conspired with a group -- People's Alliance for Democracy and Secularism (PADS) -- to sabotage the electoral process during the 2019 general elections.
Last week, the Central Bureau of Investigation took over the investigation in the case and filed an FIR in the matter. The central agency also raided two locations linked to the firm.
