A Rashtriya Swayamsevak Sangh (RSS) worker was allegedly murdered in Kerala's Thrissur on Sunday.
The RSS worker, indentified as Anand, was an accused in the murder case of a Communist Party of India (CPIM) activist four years ago.
It is to be noted that this is not the first case of violence against the workers of the right-wing group in the state.
Earlier, many similar incidents of assault have been reported that have political tension in the state.
The Bharatiya Janata Party (BJP) has been accusing the Left Government of killing the political leaders.
The saffron party had also held a rally 'JanRaksha Yatra' in Trivandrum recently to protest against alleged political killings in the state.
BJP president Amit Shah, who also participated in the rally, hit out at the LDF government and questioned whether Kerala Chief Minister Pinarayi Vijayan has come in power to kill BJP and RSS workers.
