What started as another tense weekend gathering outside a downtown Los Angeles federal complex turned into a full police operation Saturday, after officers declared an unlawful assembly on a short but highly charged stretch of Alameda Street.
The Los Angeles Police Department said “acts of criminal behavior by multiple agitators” prompted the declaration on Alameda between Aliso and Temple streets, across from the federal courthouse and Metropolitan Detention Center. Officers issued dispersal orders, made arrests, and warned drivers to brace for traffic headaches on Alameda, Aliso and Commercial as they moved in to clear the block.
⚠️Community Advisory⚠️

Due to acts of criminal behavior by multiple agitators, an Unlawful Assembly was declared on Alameda between Aliso and Temple. Dispersal Orders were issued and arrests have been made. Expect traffic delays on Alameda, Aliso and Commercial due to ongoing police action.
What LAPD Posted
The advisory went out on the department’s Central Division account on X, where police said dispersal orders were active and confirmed that arrests had been made. The same post told motorists to expect delays on Alameda, Aliso and Commercial streets while officers worked the scene, according to LAPD Central Division.
Why This Block Keeps Drawing Protests
The specific block of Alameda between Aliso and Temple has become a familiar backdrop for anti-ICE and other protests in recent months, thanks to its location in front of the federal courthouse and the Metropolitan Detention Center. Earlier confrontations and federal crowd-control efforts on the same stretch were documented during a March standoff, as reported in Feds Push Back Protesters. The complex itself is listed by the General Services Administration as the Edward R. Roybal Federal Building and U.S. Courthouse.
Legal Exposure for Protesters
Under California law, staying put at the scene of a riot or unlawful assembly after a lawful order to leave is a misdemeanor under Penal Code §409. In other words, anyone who ignores dispersal orders risks state charges. When federal officers or federal property are involved, separate federal laws can also come into play, including 18 U.S.C. §111. For more on how those statutes are applied, see summaries at ShouseLaw and the text of 18 U.S.C. §111 from the Legal Information Institute.
What To Watch Next
LAPD Central’s X account is continuing to post updates as officers manage the scene, and officials could release booking information or incident summaries later. Drivers heading into downtown should consider alternate routes and plan for slowdowns on Alameda and nearby streets while police activity remains underway, according to LAPD Central Division.
