In the second such incident in the past two days, yet another Sri Lankan boat, suspected to have been used by the LTTE, was found abandoned off the Danushkodi coast near Rameswaram on Sunday.
Indian Coast Guard personnel, who noticed the fibreglass boat near the fifth sand dune in the sea, brought it to Mandapam near here around 7 pm, police said.
Security agencies suspect that the boat could have been used by LTTE cadres, facing an all out offensive by the Sri Lankan Army in the outfit's last bastion of Mullaitheevu, to arrive here. Further investigations are on.
Yesterday, a fibreglass boat of Sri Lankan origin and fitted with a 25 Horse Power outboard engine was found washed ashore off Cherakottai. It also had four rafts and some oxygen cylinders.
An eyewitness had said one person came by the boat and fled into the casurina groves. Police said it was suspected that the person could be an LTTE operative.
The washing ashore of the boats comes at a time when the coast guard has intensified patrolling at sea and is keeping constant surveillance along the coast here following the intensification of the military offensive in Sri Lanka.
Officials said that ICG hovercrafts and interceptors had been placed on full alert.
There is apprehension among authorities that the 21 islands off the 271 km coastline between Mandapam near here and Tuticorin may be used by LTTE cadres or smugglers.
