Barishal City Corporation Mayor Sadiq Abdullah has been made prime accused in two cases filed in connection with the attack on the official residence of Barishal Sadar upazila UNO and the ensuing clash.
Upazila Nirbahi Officer (UNO) Munibur Rahman filed a case mentioning names of 28 persons, including the mayor, in addition to 70 to 80 anonymous people for the attack on his official residence at the upazila complex on Wednesday night.
Meanwhile, Kotwali Model Thana's Sub-Inspector (SI) Md Jamal filed another case showing the mayor as prime accused for obstructing government work and attacking police.
According to the case statements, the attack was conducted in the direction of Mayor Sadiq, who is also the secretary general of Barishal Metropolitan Awami League.
In connection with the cases, police have so far arrested 10 ruling party men, including Barishal City Awami League's Joint Secretary Hasan Mahmud.
The FIR filed by the UNO read that a group of 40 to 50 people in 10 to 15 motorbikes entered the upazila premises around 9.45pm on Wednesday.
The on-duty Anser member informed the UNO that the group was removing various government and political banners, including one displayed marking the National Mourning Day.
