“I did interrogate and torture him at my camp for several days. And we never recorded his arrest in the books anywhere. His [Afzal’s] description of torture at my camp is true. That was the procedure those days and we did pour petrol in his arse and gave him electric shocks. But I could not break him. He did not reveal anything to me despite our hardest possible interrogation. We tortured him enough for Gazi Baba but he did not break.”
