Security forces are deployed in all parts of the state including towns where the maximum pujas are being performed and vehicles are being checked, the sources said.
According to records available with the Agartala Municipal Council and 15 nagar panchayat authorities, about 2,200 community pujas are being organised in the state this year.
Chairman of the Agartala Municipal Council, Prafullajit Sinha said officially 351 pujas are being organised in Agartala, but the police said there are about 1000, including 81 new pujas.
"I wish puja passes off peacefully, but people should remain alert during the pujas," Chief Minister Manik Sarkar said at a function yesterday.
In 2008 Agartala was rocked by serial bomb blasts by collaborators of insurgents.
