The CBI chargesheet in the custodial death of father-son duo in Tamil Nadu has listed the brutal torture the victims endured at the hands of the cops. The CBI chargesheet says the two were subjected to "several rounds of brutal torture with intervals in between 7.45 pm and 3 am." It adds that they were beaten so brutally that blood was splattered on the walls of the police station. Jeyaraj and his son Benniks were arrested on June 19 for keeping their mobile phone shop open 15 minutes beyond curfew. They were then allegedly beaten to death at the police station.
