Villagers said a call was made from the loudspeakers at Jamia Arabia Islami Emdadul Ulum Madrasa at Rampur village near Baghsitarampur to launch the attack on Hindus.
Before the assault, leaflets were distributed for the last several days in the madrasas claiming that two Hindu youths had slandered the prophet in a Facebook post April 27.
Police arrested the principal of Bagmara Madrasa at Muradnaga in connection with the attacks. However, the main accused, Nazrul Islam, who took the lead in distributing the leaflets is still at large.
