Top police sources told rediff.com late on Wednesday night that intelligence sources had intercepted a telephone conversation in a locality near West Bengal Chief Minister Buddhadeb Bhattacharjee's home on December 1.
Sources said the conversation was about attacks on Kolkata's Victoria Memorial, Nicco Park and Salt Lake Central Park. Investigations in this matter are underway.
Kolkata police officials are also worried about the city's links with a Bangladesh-based terror outfit, Yahya. This outfit provides constant support to all Lashkar-e-Tayiba operations, intelligence sources said.
A massive hunt in the city and its adjoining areas is on to trace the buyers of the SIM cards that were used by the terrorists involved in the Mumbai attacks.
Meanwhile, the police are said to have detained a number of mobile phone outlet owners in several parts of south and south central Kolkata.
Intelligence sources also claimed that a module of Bangladesh-based Harkat-ul-Jihad-al Islami (HuJI), which has close ties with the Lashkar, has entered West Bengal, and has held secret meetings to plan how to unleash terror in the state.
