"To improve and strengthen the security system in Delhi's prisons at Tihar, Rohini district jail and the Mandoli jail complex, X-ray based full human body scanners, X-ray baggage scanners, multizone door-frame metal detectors and deep search metal detectors will soon be installed," said a statement from the Delhi government.
The Tihar complex has nine jails, and the Mandoli jail complex, housing six jails, will be operational soon.
The hi-tech equipment will help in checking smuggling of prohibited items like surgical blades, tobacco, narcotics, knives and mobile phones, it said.
The security devices have been requisitioned under the Action Plan 2014-15 submitted to the Secretary for Home under the Delhi government by the office of the Director General of Prisons of Tihar Central Jail.
The jail authorities told the government that they were facing security problems as a number of inmates were smuggling prohibited items like cell phones, blades, knives and narcotics in their body cavities.
