A division bench of Justices A M Khanwilkar and A P Bhangale directed the government to file an affidavit stating what preventive measures it proposes to undertake to prevent custodial deaths, by April.
The high court took up the issue of custodial deaths acting on a letter sent by social activist N R Soni, highlighting three custodial deaths inside the Thane central prison.
The court directive comes a week after an accused was found dead in the lock-up of suburban Chembur police station.
Two policemen have been suspended pending an inquiry against them.
