PROVIDENCE, R.I. — An alert was issued at Brown University on Saturday after reports of an active shooting on campus, leading to a swift police response. Confusion arose when officials first announced that a suspect was in custody, only to later retract that statement, indicating that the search for one or more suspects was still active. The event occurred near the Barus & Holley building, a notable facility for the School of Engineering and Physics Department, equipped with extensive laboratories and classrooms. Local authorities, including Kristy DosReis, the city’s chief public information officer, stated that they are still gathering information from the unfolding scene. The university, which has a total enrollment of approximately 10,300 students, was in the midst of its fall semester finals week at the time of the incident.
