Patrolling was intensified at the Kolkata Port Trust, the country's first major port, following the receipt of an input on `threat perception’.

The Centre has sent an alert on a possible terror threat against the city. There was no official word on this matter, amid reports that the Kolkata Port Trust, the nearly 150-year old institution was on the radar.

Senior officials of the Central Industrial Security Force (CISF), Navy, and Kolkata Port Trust (KoPT), Kolkata police’s Special Task Force(STF) and Special Branch officials held a meeting on Monday after receiving an alert from the Centre, police sources told The Hindu.“ The alert is of a general kind and no particular threat has been specified,” the source said. The KoPT has decided to intensify its vigilance and patrolling following the receipt of an input on ‘threat perception’ at the port and its installations. The alert was received on Monday evening.

Sources told The Hindu that after receiving the alert, the port authorities held a meeting to review security arrangements.

The Navy pulled out INS Khukri and INS Sumitra, which had called on Kolkata port on Monday evening to take part in the Navy Week observances, and deployed them to scour the seas in the wake of the terror alert.
