The presiding officer and two assistant presiding officers of a polling centre in Sirajganj sadar upazila, who had been arrested on charges of electoral fraud in the upazila parishad elections, were sent to jail on Monday.

Sirajganj sadar was one of the 78 upazilas where the first phase of upazila parishad elections took place on Sunday.
In the early hours of the election day, upon hearing allegations of election rigging and irregularities, a team of police and Rapid Action Battalion (RAB) conducted a drive at Mahmudpur Government Primary School polling centre, Sirajganj district Election Officer Abul Hossain told the Dhaka Tribune on Sunday.
During the raid, Election Officer Abul Hossain and Executive Magistrate Rahmat Ullah caught the trio red-handed while stuffing ballot.
Following the arrest, Returning Officer Firoz Mahmud, also the additional deputy commissioner in Sirajganj, suspended voting in the polling centre at around 2am on Sunday – only hours before the polling was scheduled to start.
Assitant Returning Officer Sarker Mohammad Raihan, also upazila nirbahi officer in Sirajganj sadar, filed a case against the accused with Sadar police station under Section 79 (D) of Upazila Parishad Election Guidelines, 2013.
