If you read more reports you will see he was arrested on the charge of impersonating an army officer as seen on many of his Facebook posts as well as his own messages boasting about his army pedigree. This is not only a crime under Indian Law (possibly other countries too) but incredibly stupid where he could have suffered bodily harm in an environment where terrorists have been known to impersonate the army & attack the Parliament. As far an earlier comments of bamboo sticks & torture du jour, thankfully due to the same medium we all discuss (forms internet & social media) this has become extremely risky for the police to do & has actually tamed them a lot...... mental harassment is another case & usually kept exclusively to the multiple white collar crimes that are being caught.
