In an exclusive interview to OneIndia News, Muthi said that during his six months stay at Parappana Agrahara Central jail, Bangalore, police used mental torture to get confession from him.
"I was not physically tortured. But, I went through severe mental torture and anguish in the jail," said Muthi, who was earlier working with a leading Bangalore-based English newspaper, before his arrest.
However, he added that others who were arrested with him went through physical torture in the jail.
Muthi said police used to intimidate him to make confessions. "I am happy that I did not bow down to pressure and remained firm in my stand. However, some of my friends were forced to make false confession, under pressure."
Muthi said they were given no reason for their arrest as per law. He said all of them were made to sign 30-40 blank papers and were later surprised when one such paper was used as an arrest memo.
