The son of one of the victims in the Kuniyil twin murder case was stabbed by unidentified persons at Mukkom, 30 km from the city, on Thursday night.

The police said Gulam Hussein, 30, son of Kolakkadan Aboobacker, was attacked by a gang when he was returning on his motorbike from Mukkom to his house at Kuniyil. The assailants could have waylaid him at Karuthaparambu Angadi around 11 p.m.

The seriously injured youth was admitted to the Kozhikode Medical College Hospital. An emergency surgery was carried out following a deep gash in the abdomen.

The Mukkom police have registered a case under Section 307 (attempt to murder), 143 (unlawful assembly), 146 (rioting) and 148 (rioting, armed with weapons) of the Indian Penal Code.

No one has been arrested so far. Investigation was on, the police said.

Investigators said that some of the witnesses said that a gang had intercepted Gulam’s motorbike at the junction.

He was attacked with a dagger by one of them after a quarrel. He almost ran 100 metres before falling down on the road.

The local people took him to the hospital.

Kolakkadan Aboobacker and Kolakkadan Azad were stabbed to death at Kuniyil New Bazaar by a masked gang on June 10, 2012. The twin murder was reported to be in retaliation for the killing of Atheek Rahman, an Indian Union Muslim League activist, on January 5, 2012, at Kuniyil in the wake of dispute over a football match.
