Three persons, identified as Sugumar, 27, Palpandi, 22, and Selvendran, 60, of Vairavanpatti were arrested on Friday in connection with the murder of Muthupandi, 45, a BJP functionary, on Thursday.
A three-member police team was formed to nab the killers. CCTV footage showed that six people had attacked the victim at a tea stall and escaped in two motorcycles. Police said that it was a murder for revenge.
On July 9, 2012, Selvam of Vairavanpatti was coming on a two-wheeler to the Sivaganga district sessions court to appear in a murder case. He was waylaid and murdered and Muthupandi figured as an accused in the crime.
In a retaliatory act, the trio, suspected to be relatives of Selvam, had allegedly murdered Muthupandi and settled the score, police added.
A senior police officer said that they were on the lookout for three more people in this connection and were yet to seize the two-wheelers and weapons.
It is said that Selvam had murdered Ponnusami, a former AIADMK union secretary.
