Tension in the district, following the assault on Communist Party of India (Marxist) leaders near Taliparamba here on Monday morning, escalated with the murder of an Indian Union Muslim League (IUML) worker from Ariyil in the afternoon.

The police said that IUML worker A. Shukkoor, 22, from Ariyil, was found dead with stab injuries at Vallavamkadavu under the Kannapuram police station limits here. He was allegedly stabbed to death by CPI(M) workers possibly in retaliation to the manhandling of the CPI(M) leaders at Ariyil by suspected IUML workers.

The police said that another IUML worker, identified as Sakariya, 23, also suffered stab injuries at Vallavamkadavu around 3.45 p.m.

He was admitted to the Mission Hospital at Kannapuram.
