The alert was issued after the LAPD officially declares the protests an "unlawful assembly."

President Trump also deployed the National Guard to California overnight. The guard members' arrival come as the Trump administration declared it will send the National Guard in response to the protests that took place in Paramount, downtown Los Angeles and Westlake over the last 48 hours. The protests have led to tense clashes between federal law enforcement, protesters and alleged agitators with no ties to immigration advocacy.

The clashes between federal law enforcement and civilians come as border patrol officers have made their way to Southern California in gray SUVs and attire resembling riot gear this weekend. Their presence has alarmed Angelenos, prompting witnesses and activists to suspect the staging of ICE raids.
