Three persons were arrested early today in connection with the killing of an RSS worker at Nenmeni near the temple town of Guruvayur in Kerala, police said.

The 23-year-old Anandan, who was riding a motorcycle, had been knocked down by a car carrying his attackers and then hacked to death on November 12.

Those arrested included a brother of Fazil, who was killed four years ago and Anandan was an accused in that case. The arrested are identified as Faiz, Karthik and Jitesh, a top police official said. Asked whether the three were CPI(M) workers, the official said it had not yet been substantiated. -- PTI
