The Madras high court on Tuesday said that there are grounds to charge Tamil Nadu policemen with murder for the custody death of a father-son duo in Tuticorin. The court made the observation based on the post-mortem report. Two police officers are "on wait" and a constable has been suspended for allegedly trying to block investigations into the deaths. All three were summoned by the court on Tuesday. 59-yr-old Jeyaraj and his 31-yr-old son Beniks were allegedly tortured at police station after being arrested for keeping their mobile shop open beyond permissible hours.
