New Delhi: For some criminals, even jail doesn't serve as a deterrent. They are adopting new methods to carry out illegal activities inside the jail. In a shocking incident, a prisoner at Delhi's Mandoli jail hid a surgical blade in his stomach.

The matter came to light on Tuesday when an undertrial inmate named Sunil alias "Chooha", a resident of Trilokpuri, returned to the jail after appearing in a court hearing.
