Police probing the murder of BJP state secretary V Ramesh suspect the involvement of three persons, including two accused in the planting of a 'pipe bomb' during party leader LK Advani's visit to Madurai in 2011.
Fakruddin alias 'police Fakruddin', Bilal Malik (both of Madurai) and Panna Ismail of Melapalayam in Tirunelveli district are suspected to be involved in the murder of Ramesh, Salem superintendent of police R Shaktivel said.
Anybody knowing their whereabouts can inform police and they would be suitably rewarded, Shaktivel said.
Ramesh (52) was hacked to death while he was returning home after visiting the BJP office on Friday night in Salem that sparked an outrage in the part which gave a call for a state-wide bandh on July 22.
A total of 17 stab injuries were found on the body which was cremated yesterday.
Some three to four persons had murdered him, Shaktivel said.
The BJP has demanded the Tamil Nadu government order a judicial probe into the murder, which was condemned by the party's national leaders.
Gujarat chief minister and party's election campaign chief Narendra Modi, and Leader of Opposition in the Lok Sabha Sushma Swaraj have also demanded action against the guilty.
Police had discovered a pipe bomb from under a bridge and defused it on October 27, 2011 at Alampatti village, about 30 km from Madurai on the route of Advani's 'Jan Chetna yatra.' Subsequently, the BJP leader's route was diverted.
