Ten top leaders of Khelafat Majlish were arrested in the past 24 hours until Thursday morning in connection with the clashes and vandalism carried out by Hefazat-e-Islam men in Brahmanbaria last month.
Md Abu Taher, President of Sarail Upazila Khelafat Majlish confessed to his involvement in Brahmanbaria mayhem, saying it was a part of a conspiracy to oust the government from power, said police.
Besides, nine more Hefazat activists were arrested, reports UNB.
So far, 55 cases have been filed and 434 people arrested over the violence, said a press release of Brahmanbaria police.
On March 27, at least five people were killed and around 50 others, including 25 policemen, injured in clashes between members of the law enforcement agencies and locals during Hefazat's demonstrations at Nandanpur in Sadar upazila.
They had staged the protests against Indian Prime Minister Narendra Modi's Bangladesh visit.
The next day, during Hefazat's countrywide dawn-to-dusk general strike, against police action on their anti-Modi processions in Dhaka, the organisation's activists in Chattogram and other districts set three buildings on fire, including the land office in Brahmanbaria Sadar upazila.
They had also attacked a Chattogram-bound train at Talshohor Rail Station in Brahmanbaria town.
