Despite the installations of gadgets, prisoners managed to smuggle contraband into the jail. Indo-Tibetan Border Police trained Labrador and Stately Alsatians have been put on duty to watch offenders.
"The Labradors and Stately Alsatians of the ITBP that are trained at its National Dog Training Centre in Bhanu will be able to trace drugs smuggled by notorious inmates in body cavities and which remain undetected by normal detectors," said RN Sharma, Deputy Inspector General of Tihar Prisons.
"They are trained to be alert on more than one kind of drug. These trained dogs can locate drugs concealed in body cavities too," Sharma said.
Tihar Jail is Asia's largest prison and different types of drugs and narcotics including opium, sulfa, charas, cocaine, smack etc are reportedly being distributed in the jail.
"There has been incidences when prisoner or their visitors have carried in drugs which were not detected. In such cases, these specially trained dogs will work wonders. They can sniff and tell.
"These canines have a sophisticated sniffing system for detection of drugs and explosives. They exceed the human sense of smell and in today's high-tech world, trained dogs are still the best narcotics detectors with accuracy of over 90 per cent," the Inspector General added.
