A local committee office of CPI-M at Beliaghata was ransacked this evening by a group of unknown miscreants and they also beat up partymen, the police said.
The miscreants opened fire and chased some party members, sources said.
CPI-M leader and former state minister Manab Mukherjee visited the spot and later alleged about involvement of Trinamool Congress-backed anti-social elements behind the incident.
"It was the handiwork of Trinamool Congress to foil our party's plan to organise a rally in the area," he said.
Trinamool Congress sources denied the allegations of Mukherjee and nobody was arrested.
