"The Commission has taken suo motu cognisance of media reports that there are about 20 gangs of inmates operating inside the Tihar jail who facilitate mobile phones, coolers, porn magazines and protection from sexual abuse to prisoners who can pay them," the NHRC said in a statement.
They even plot crimes, including murder, both inside and outside the prison, it said.
Notices have been issued to Principal Secretary (Home) and Director General (Prisons) and a report has been sought in this regard within two weeks, it said.
The Commission has also authorized one of the SSPs in the Investigation Division to conduct an inspection of Tihar jail and verify the allegations.
According to media reports, 17 deaths have taken place inside the jail in the last four months, raising serious questions about the much needed security infrastructure.
