At approximately 10:00 pm, several hundred demonstrators began gathering outside North Precinct near Northeast Emerson Street and Northeast Martin Luther King Boulevard. Demonstrators arrived with supplies to build a fence and began erecting one which stretched from the south side of North Precinct to the north side of the Boys and Girls Club. While building the fence, demonstrators blocked northbound traffic at Northeast MLK Boulevard. During this time, demonstrators began throwing projectiles at police including glass bottles.
By 11:00 p.m., demonstrators began moving dumpsters and other large barriers around North Precinct. Some demonstrators began ramming the dumpsters into large garage doors located on the west side of the North Precinct in an attempt to breach the building. Demonstrators were not successful at breeching the doors so they turned their attention to barricading exit doors so officers inside the building, as well as people in custody, could not get out.
By 12:00 a.m., a demonstrator in the crowd outside North Precinct began yelling over a bullhorn that they were “going to burn the building down“. Several demonstrators in the crowd were wearing masks and yielding shields. Fireworks were thrown at Officers over the barricade they had built on Northeast Emerson Street.
Around 1:00 a.m., there were still several hundred demonstrators in the crowd surrounding North Precinct. Due to life safety issues, the sound truck made an admonishment stating an unlawful assembly had been declared, instructing the crowd they needed to leave the area immediately or they could be subject to use of force or arrest.
