In the Kandi area of Murshidabad district, clashes broke out when the participants in a Ram Navami rally, allegedly armed with swords and tridents, tried to enter a police station, the police said.
At least 10 persons were injured when the members of the Ram Navami Utsav Committee came to blows with the police personnel during a procession in the area, a senior police officer said.
The committee, also comprising BJP and VHP activists, had organised the rally from the Kandi bus stand to the Radhaballav temple around 11.30 am, Additional SP (Sadar) Anish Sarkar said.
"A clash ensued between the two sides as a few participants of the rally hurled stones at the police station and the vehicles parked outside. The police had to baton-charge the agitators," he said, adding that no one was arrested in connection with the incident so far.
BJP leader Subhash Mondal, however, blamed the local members of the ruling Trinamool Congress (TMC) for the ruckus.
"Unidentified miscreants of the TMC joined the rally to create a ruckus. It was an attempt to spoil our image before the people here," he alleged.
Refuting Mondal's allegations, TMC MLA Apurbo Sarkar accused the BJP and the VHP of trying to disturb peace in the area and claimed that the ruling party had nothing to do with the incident.

The members of the two communities got into a fight even as the police tried to intervene, he said, adding that a temple in the vicinity was also attacked during the clashes.
"Asansol-Durgapur Deputy Commissioner of Police Arindam Dutta Chowdhury was injured in the incident. He lost a hand when the agitators hurled a bomb at him. He has been admitted to a private hospital," the officer said.
Officer in-charge (OC) Pramit Ganguly also received head injuries in the violence, he added.
Union minister and Asansol MP (BJP) Babul Supriyo, who was supposed to participate in one the rallies in Raniganj but backed out at the last moment, alleged that it was a "premeditated attack, meant to hurt me".
Asansol Mayor Jitendra Tiwari urged the people to maintain peace in the area.
The TMC and the BJP had organised several processions to celebrate Ram Navami in the state, with the saffron party dubbing the rallies as a first step towards "uniting the Hindus" of Bengal.
State BJP president Dilip Ghosh said it was an age-old Hindu tradition to conduct "astra puja" (worship of weapons) on the day of Ram Navami and that he was not aware of any ban on armed rallies.
"Where is the government order banning arms in Ram Navami processions? Where is the circular?" he asked.
A case was also registered against BJP West Bengal Mahila Morcha president Locket Chatterjee today for allegedly participating in an armed Ram Navami procession in Birbhum district yesterday, Superintendent of Police (SP) N Sudheer Kumar said.

The police would take legal action against those who defied the rules, he added.
