According to the data, Uttar Pradesh reported the maximum number of deaths with 331 deaths at police and judicial custody. Meanwhile, Maharashtra was the only state to record more than 30 deaths in police custody.
The NHRC submitted the data in the ongoing session of the Rajya Sabha in response to MP HK Dua's query.
“We collect the data on the basis of individual complaints as well as those sent by prison authorities. The most complaints were sent from UP,” said an NHRC official.
Andhra Pradesh, Bihar and Maharashtra are the other states where more than 100 custodial deaths were reported.
“Once we have received the intimation about any custodial death, we conduct our independent inquiry and prepare a report. If any official is found guilty, we send advice to the district administration. The NHRC also calls for reports for ascertaining any foul play or negligence," the official added.
