A wooden barricade has been erected along the coast in Mamallapuram beach as a precautionary measure in view of the forthcoming kaanum pongal celebrations.
According to official sources, a large number of holiday revellers gathered at this beach abutting the Archaeological Survey of India-maintained Shore Temple monument on kaanum pongal day in past years.
Often, people also attempt to swim in the sea.
But after the tsunami in 2001, the shore had deepened at several places beneath the waves making it dangerous for revellers to venture into the sea.
Signboards have been erected near the Shore Temple warning the public not to go anywhere near the sea.
On Sunday, three women from Bangalore lost their lives when they went swimming near the location.
Following this, the Mamallapuram town panchayat and the police have decided to erect the barricade along the coast to check the movement of people.
Police personnel would be positioned between the sea and the barricade during the Pongal holidays to thwart any attempt to venture into the sea, the sources said.
