The state leadership was forced to summon workers from the party's Howrah unit to free Sinha who was gheraoed in his office by dissident party workers aggrieved over ticket distribution.
The workers arrived when the dissident workers were preparing to organise a sit-in demonstration outside the party office.
"What would we have done, if some party workers behave in an unruly way? So party workers from Howrah came and freed us. Whatever the party workers of Howrah unit has done is right. I feel even if they had beaten someone, then they had done the right thing," Sinha said.
"We will not tolerate dissent or indiscipline in the party. Actually when the ticket distribution took place, a few people were unhappy as they didn't get tickets. We thought they will shout slogans and the matter will die down. We allowed them to show their anger but now the matter has gone too far," Sinha told a press conference amid a din of slogans raised against him.
Sinha said the party would prefer not to field any candidate in some places, rather than surrender to indiscipline within the party.
The demonstrators alleged that a section of state leaders were taking money in exchange for tickets.
Sinha accused the CPI-M and the TMC of fuelling dissent and protests against the party leadership in the districts and the city.
Meanwhile, the BJP state leadership accepted the resignation of the party's Birbhum district president Dudh Kumar Mondal, who put in his papers accusing a section of party leadership of being involved in corruption over ticket distribution.
