The Election Commission (EC) has reported irregularities and disturbances at 37 voting places around the country.
The EC control room provided the findings around 11:30 am on Sunday.
Six people have been arrested on suspicion of voting fraudulently, adding to the concern. One of those arrested had already been sentenced to six months in prison in Barguna.
A female chairman was detained in Chattogram in relation to offenses relating to elections.
In the meantime, two people, Abdur Rahim and Zakir Hossain, were taken into custody at the Meherganj Government Primary School Center in Lalmohan, Bhola, for trying to give polling agents "proxies" without the required signature of the presiding officer.
Deputy Secretary Sujit Halder made a personal visit to the center at 10:00 am, which facilitated the arrest and later handed them over to the police.
