The entire Kerala coast was put on high alert on Sunday evening after Central intelligence agencies alerted the state police on a possible attempt by Sri Lankans to sneak into the state through the coastal regions.

Sources with the Intelligence agencies said the alert was issued from Chennai after inputs that a group of 25 persons from Sri Lanka would attempt to enter the country through the coastal regions in Tamil Nadu and Kerala.

“There is no specific input that the persons will be LTTE suspects. But as the persons are supposedly Sri Lankan Tamils, the state police and coastal patrolling agencies have been directed to maintain tight vigil,” sources said.

With Tamil Nadu sealing the entire coastal areas in the wake of the alert, there was a possibility for the intruders to eye the coastal regions in Kerala. Meanwhile, city police officials said they had directed coastal patrol boats to conduct a round-the-clock surveillance of the coastal regions and alerted the coastal people to alert the police if they found any boat in suspicious circumstances.

The city police also conducted a thorough search in the lodges and hotels in the city to collect information about their inmates. “Vehicles were searched as part of the surveillance,” police sources said, ENS reports.
