Jasim Uddin, deputy-commissioner of Chattogram City West Zone, said a group of Jamaat Shibir activists gathered in front of Akhtaruzzaman Shopping Complex with a banner and brought out a sudden procession.

“Legal action will be taken in this regard,” added the commissioner .

Earlier, Jamaat-e-Islami sought permission from Chattogram Metropolitan Police to hold a rally in the port city’s Laldighi ground on July 22.

Jamaat leaders have reportedly lent support to BNP’s grand rally and vociferously echoed BNP’s demand of removal of the government and installation of the caretaker system as precondition for any polls.

During the 2014 national elections, BNP-Jamaat combine reportedly carried out attacks on polling stations, coupled with attacks on minorities and law enforcers.
