The BJP on Tuesday organised Shahid Samman Yatra across West Bengal to protest against alleged post-poll violence in the state. The minister participated in the yatra at Gouripur in North 24 Parganas district. The police said they stopped the demonstrators for protesting despite not receiving permission to hold the event, and took some of them into a prison van. Thakur himself jumped into the van and went to the police station, the police added. The Bongaon MP later held a sit-in. Later in the day, all the BJP workers and leaders were released. After getting out of the station, Thakur alleged that he was illegally detained for more than two hours. I came here to offer puja and was arrested by the police. If I had got arrested on my own then why are so many other workers here with me? The police told me that I was doing illegal work…, he said. One the other side TMC spokesperson Kunal Ghosh said, I have no information that Thakur has been arrested. I saw one MP jumped into the prison van. This is cheap publicity.
