Kolkata: The BJP today sought the intervention of West Bengal Governor KN Tripathi over Sunday's violence at Kaliachak in Malda district and requested him to speak to Chief Minister Mamata Banerjee.
Ruling Trinamool Congress (TMC) on the other hand said any attempt to foment trouble would not be tolerated.
Violence had broken out at Kaliachak on Sunday over an alleged remark of a BJP leader, police said.
"We have sought his (Tripathi's) intervention in the Kaliachak incident and requested him to speak to the chief minister directly in this regard," BJP national secretary Rahul Sinha told reporters in Kolkata after meeting the Governor at the Raj Bhavan with a party delegation.
Accusing the Trinamool government of shielding those behind the Kaliachak violence, he alleged that the Kaliachak police station was set on fire with the intention to destroy all criminal records and the prime suspects have not been arrested.
Mr Sinha questioned why intellectuals were silent on this issue when they staged nation-wide demonstrations and returned awards in protest against alleged intolerance and beef eating issues.
During the day a 25-member BJP delegation led by its lone legislator Shamik Bhattacharya was detained by the police when they were trying to enter Kaliachak. They were released after about 10 minutes.
Mr Bhattacharya said the delegation had gone to Kaliachak to know about the exact reason for the incident but was not allowed to enter.
When contacted Trinamool lawmaker and party's observer for Malda district Subhendu Adhikari declined to comment on the incident but said that the administration had taken appropriate steps.
"Any attempt by the opposition to foment trouble in the state would not be tolerated," he told PTI.
State Congress president Adhir Chowdhury alleged that the BJP was trying to foment majority communalism, while the Trinamool Congress was "encouraging minority fundamentalism".
"We will fight against it by mobilising secular and democratic people," he told the news agency.
Asked about Ms Banerjee calling up Mr Bhattacharya while he was at the police station at Kaliachak, state BJP president Dilip Ghosh said "The chief minister called him up because she is scared thinking that it may affect her party's fate in the coming (assembly) polls."
The CPI(M) leadership lashed out at the state administration and said there is "complete lawlessness" in the state.
"The incident itself proves complete lawlessness in the state. The law and order mechanism has completely broken down. The state government didn't take any concrete steps to avert the situation," CPI(M) Politburo member Mohammed Salim told PTI.
He also alleged that police administration in order to cover up the incident is now harassing the common people.
"Both BJP and TMC are trying to spread the poison of communalism in the state and such incidents will increase as the assembly election approaches," Mr Salim said.
