The crackdown was jointly led by the Local Crime Branch (LCB) and the Anti-Narcotics Cell of Raigad police following a tip-off received by constable Iqbal Shaikh of Mahad MIDC police station. Acting swiftly, multiple teams carried out a coordinated raid on July 23. Inside the chemical unit, officers discovered the banned psychotropic drug ketamine being illegally produced in violation of the Narcotic Drugs and Psychotropic Substances (NDPS) Act.
