CALIFORNIA—The Los Angeles Police Department declared a tactical alert within the city following incidences of vandalism and physical assaults directed at police officers. 

According to the LAPD, concern about Saturday’s protests mounted at around 5:30 p.m. when “Refuse Fascism” protesters “began to direct physical assaults on officers deployed to facilitate the demonstration, vandalize property, and walk onto a busy freeway.” At 7 p.m., the LAPD declared a tactical alert in response.

Earlier into the demonstrations, a small subsection of protesters splintered and marched toward the U.S. Courthouse on First Street where they broke windows and spray-painted exterior walls, KTLA reported.

The LAPD announced they arrested four people from the protests. Three were for battery on a police officer, and one was for carrying a machete and causing a disturbance. 

This alert comes as protests in Portland have been intensifying and have even been declared a “riot” by local authorities. By 9:30 p.m., the protests began to diminish and end.
