At about 2 p.m. on Sunday, September 28, 1919, a large group of white youths gathered near the Bancroft School in South Omaha and began a march to the Douglas County Courthouse, where Brown was being held. The march was intercepted by John T. Dunn, chief of the Omaha Detective Bureau, and his subordinates. Dunn attempted to disperse the crowd, but they ignored his warning and marched on. Thirty police officers were guarding the courthouse when the marchers arrived. By 4 p.m., the crowd had grown much larger. Members of the crowd bantered with the officers until the police were convinced that the crowd posed no serious threat. A report to that effect was made to the central police station, and the captain in charge sent fifty reserve officers home for the day.[citation needed]
