Protesters vandalised the Jatiya Party's (JaPa) office in Khulna's Dakbangla area on Saturday evening.
Sheikh Munir-ul-Gias, the officer-in-charge of the Khulna police station, said that a group of agitated individuals attacked the Jatiya Party office around 6pm. They hurled bricks at the building, removed two plastic chairs from inside, and set them ablaze.
