Some 90 people, including Awami League and BNP men, were accused in a case on Monday over “setting fire to an election camp” of Narayanganj-5 grand alliance candidate Salim Osman.

However, firefighters said only a few posters were burnt in the incident and locals doused the flames before they arrived at the scene.

Kamrul Islam, officer-in-charge of Narayanganj Model Police Station, said local resident Enamul Haque Riaz filed the case against 74 named and some 10 to 15 unnamed people in connection with the incident.

Most of the accused are the leaders and activists of Narayanganj BNP and the AL. District Gonoforum President Delwar Hossain Chunnu, Bandar Thana AL organising secretaries Humayan Kabir Alin and Anwar Hossain, Jubo League leaders Motalib and Himel Khan, Bandar Thana Chhatra League Senior Vice President Mia Babu, Kadamrasul Municipality Jubo League Vice President Masum and district Bangabandhu Foundation Information Secretary Rabbi were named in the case.

Many of the accused were seen forming a human shield around Narayanganj City Corporation Mayor Selina Hayat Ivy during an attack on her in the city's Chashara area on January 16.

“We have been made accused in the case as we are supporters of the mayor,” said accused Himel.

Meanwhile, police arrested Gonoforum leader Chunnu from his city house on Monday night, just around an hour after the case was filed.

Talking to The Daily Star, Narayanganj Fire Service Deputy Assistant Director Abdullah Al Arefin said only some posters near Selim Osman's election camp were burnt in the fire which was doused by locals before they arrived at the scene.
