Chhatra Dal leader Rakib Sardar has been expelled from his party position for allegedly violating Section 144 by entering an HSC examination center in Natore. The regulation prohibits unauthorized access within 100 yards of the exam venue. Sardar claimed he entered to help his cousin find her seat. However, officials confirmed his presence during the exam. The local UNO has reportedly issued a show-cause notice to the exam center secretary over the incident.
