The Mararikulam assembly constitutency is represented by Kerala Finance Minister Thomas Issac.
The trouble started this morning after local people, led by DYFI activists, pelted stones at 'Palm Fibre', a major export-oriented coir factory. The local people were protesting against the alleged encroachment by the factory on public land.
As police failed to check the stone-pelting, the agitated workers of the company came out to resist the attackers and clashed with them. Three people were reportedly injured in the clash.
