His cover was blown after Indian intelligence sent another agent Inyat Masiha, to get in touch with Black Tiger. But the agent was caught by Pakistan's intelligence agencies and revealed Ravinder Kaushik's true identity.
Kaushik was then captured, tortured for two years at an interrogation centre in Sialkot. Ravinder was awarded death sentence in the year 1985. His sentence was later commuted to a life term by the Pakistan Supreme court.
Kaushik was kept in various jails, including Sialkot, Kot Lakhpat and in Mianwali jail for 16 years, where he contracted Asthma and TB.
The brave spy managed to secretly send letters to his family in India, from inside the Pakistan jail, which revealed his poor health condition and the trauma faced by him in Pakistani jails.
