The doors and windows of the party's Tapsi-II Anchalik office were shattered by the impact of the blast early this morning, the police said.
However, no casualties were reported in the incident as the office was closed then.
TMC leaders have lodged a complaint with Jamuria police in this regard with party leader Monojit Chattopadhyay alleging that it was the handiwork of BJP workers in the area.
The area falls under Asansol Lok Sabha constituency which was won by BJP leader and Union Minister of State for Urban Development Babul Supriyo.
In a separate incident in Kolkata, fire broke out in a TMC office near Dinabandhu Andrews College on Raja Subodh Mullick Road in Jadavpur last night.
Some documents and furniture were damaged in the fire caused due to a short-circuit, police said.
