Section 144 of CrPC empowers the executive magistrate to prohibit the unlawful assembly of five or more people in the area in which it is imposed. After the imposition of section 144, obstructing police from taking such unlawful assembly is also a punishable offence. Such members can also be booked for “engaging in rioting”.
