Rapid Action Battalion (RAB) in a press briefing on Saturday disclosed that the attack on Hindu community in Rangpur's Pirganj was totally pre-planned.
The elite force made the statement a day after the arrest of the masterminds behind the attack - Saikat Mandal and his associate Robiul Islam.
RAB Legal and Media Wing Director Commander Khandaker Al Moin told journalists that arrested Saikat used to make provocative posts on Facebook regularly. After the Cumilla incident, he made another post on Facebook. The controversial post reached around 3,000 followers on social media inciting violence. He asked Rabiul to use a loudspeaker to make a provoking speech and gather a mob. After the attack, he went into hiding.
According to the RAB officials, prior to the attack and arson, Robiul provoked the villagers with various lies and rumours through loudspeaker and asked them to gather to take part in the attack. He then gave the responsibility of miking to one of his reliable cohorts and led the attack on the Hindu community. Later, he fled the scene.
