Six CPI-M workers were arrested last night in connection with the murder of a 27-year-old RSS worker in poll-bound Kerala’s Kannur district. Two incidents of bombs being hurled were also reported yesterday. Police made the arrests late night in Thalassery.

Police said a 20-member gang was involved in the attack on Sujit, an RSS worker who was killed in the attack on last Tuesday morning.

A group of miscreants had barged into the house of Sujit at Papinesseri in the district and hacked him in front of his aged parents and brother. Sujit later succumbed to injuries in the hospital.
