Death of Manju Shette, an inmate at Byculla women's prison in central Mumbai, had triggered protests by other prisoners.
Shette, 45 died at the government-run J J Hospital on June 23 following alleged beatings by jail staffers after she failed to account for two eggs and five loaves of bread which she was supposed to distribute to other inmates.
Her death had triggered a protest by around 200 inmates of the jail on June 24 with some of them climbing atop the prison's roof and others making a bonfire of newspapers to vent out their anger.
