Aryan Khan was in jail because he was arrested on October 3, 2021, in connection with a drugs case after a raid conducted by the Narcotics Control Bureau (NCB) on a cruise ship off the Mumbai coast. He was accused of involvement in the consumption, sale, and purchase of narcotic drugs. He was charged under several sections of the Narcotic Drugs and Psychotropic Substances (NDPS) Act related to possession and consumption of drugs. Aryan Khan spent 22 days in Mumbai's Arthur Road Jail before being granted bail by the Bombay High Court on October 28, 2021. Eventually, the case against him did not find sufficient evidence to continue, and the charges were dropped in May 2022.
During his jail time, Aryan Khan was reportedly in a difficult and unsafe environment surrounded by criminals, and he was helped and protected by other inmates like Ajaz Khan. The case drew extensive media attention and had political and public controversy around the investigation and handling by the NCB.
