Multiple people were arrested Saturday during a demonstration outside Atlantic City police headquarters, but the exact number of arrests and the full circumstances surrounding them remained unclear late Saturday as published accounts differed and police had not released a detailed public account. The demonstration was organized by immigrant-rights group El Pueblo Unido following a dispute over a traffic stop involving the group's executive director, Cristian Moreno-Rodriguez, as he was monitoring federal immigration enforcement activity in Atlantic City. Moreno-Rodriguez was among those taken into custody Saturday. The Press of Atlantic City reported five arrests during the demonstration. BreakingAC reported at least four.
