Bharatiya Janata Party (BJP) activist T. J. Jijesh's house was attacked earlier today.
Three two-wheelers that were parked in front of the house reportedly caught fire during the attack.
The BJP has alleged that the Communist Party of India (Marxist) (CPI-M) was behind the attack.
An investigation is underway.
