According to the police, Nirmal was on the outskirts of the city during a temple festival. Though the youth was rushed to the hospital, his life could not be saved. Another worker Thomas, 29, was also injured in the attack.
The incident occurred a month after a BJP worker was attacked and killed outside his home in Kannur district. C Santhosh, 52 was attacked by gang last month.
Few days back a BJP team from the state had visited Union Home Minister Rajnath Singh complaining that the state police force was unproductive and the CPI (M) was indulging in state-sponsored violence.
