Two supporters of Subbash Pannayar were beheaded in the clash at Pazhayakayal village on March 8 in which bombs and country weapons were freely used and their heads placed before a portrait of Dalit leader Pasupathipandian.
The clash was a fallout of the murder of Pasupathipandian near Dindigul some years ago.
Supporters of Pasupathipandian barged into the garden of Subbash Pannayar, hurling country bombs to disperse his supporters.
While doing so, they severed the heads of two supporters of Subbash Pannayar and gave it as an 'offering' to a portrait of Pasupathipandian on the roadside.
Subbash Pannayar was one of the accused in the murder of Pasupathipandian.
Kannan alias Kandasamy, Manikandan and Murugan surrendered before a Judicial Magistrate Court this after noon and later remanded to custody, police said.
