The Enforcement Directorate (ED) and Income Tax (I-T) Department are likely to join the Assam Police in investigating alleged organised financial crimes and acquisition of benami properties by event manager Shyamkanu Mahanta, an accused in the death of Assam's cultural icon Zubeen Garg. The Criminal Investigation Department (CID) of Assam Police has also unearthed more than 20-year-old financial irregularities allegedly committed by Mahanta during his earlier job at a non-banking financial company (NBFC).
