A high intensity explosion destroyed a Trinamool Congress party office in Birbhum district Monday, police said.
The incident took place at Barrah village under Kankartala police station area. It is yet to be ascertained if anyone has been injured in the explosion, police said.
The party office was locked from outside when the explosion, which damaged a big portion of the office, occurred, they said.
"The local people claimed that the office was locked at the time of explosion," Kunal Agarwal, Superintendent of Police, Birbhum, said,
"To ensure the nature of explosion some more time is required. So far, no person has been arrested in this connection," he added.
Anubrata Mondal, the district TMC president, alleged that BJP-backed criminals from Jharkhand attacked the party office with bombs.
District BJP president Ramkrishna Roy described Mr Mondals allegation as "ridiculous".
