The Enforcement Directorate has initiated a money laundering probe into an international drug trafficking racket allegedly involving a former DMK functionary. The case, filed under the PMLA, follows multiple FIRs, including one by the NCB involving Jaffer Sadiq's arrest for smuggling pseudoephedrine worth Rs 2,000 crore. Sadiq's connections with film financiers, "high profile" individuals, and political funding are under scrutiny. The NCB is expected to summon a senior DMK official regarding transactions with Sadiq. The DMK has distanced itself from Sadiq, who was expelled in February.
