In the NESCO music concert drug overdose death case, a court has extended the police custody of four alleged drug suppliers, Ayush Sahitya, Shubh Agarwal, Vineet Gerelani, and Anand Patel, till April 23, as investigators widen the probe into what now appears to be a larger drug syndicate.

The case has now seen 10 arrests, with the latest being a bouncer, Pradeep Gupta, who is accused of running a “backdoor entry” racket.
