Police say 50 people were arrested following a protest in downtown Los Angeles on Saturday night.

Police say 50 people were arrested -- mostly for failing to disperse, along with arrests for assault with a deadly weapon and vandalism -- following a protest in downtown Los Angeles on Saturday night.

Several streets near the federal building were closed overnight but have since reopened.

Tensions escalated after agitators began throwing fireworks, rocks and bottles at officers, according to LAPD.

AIR7 video showed fireworks going off in the area.

Following another protest on Friday, LAPD said eight people were arrested. One person was taken into custody for assault with a deadly weapon on an officer, one was arrested for a curfew violation, and six people were arrested for failure to disperse.

According to Los Angeles police, officers were making arrests of people who failed to disperse when the first dispersal order was issued in the area.

AIR7 video shows several people with their hands behind their backs in handcuffs, lined up along Alameda Street, north of Temple Street.

The arrests come after another chaotic night in downtown L.A. Federal agents deployed tear gas near the federal detention center after agitators in the crowd began throwing fireworks, rocks and bottles at them, according to police.

LAPD declared an unlawful assembly and multiple dispersal orders have been issued.

The city of Los Angeles is now on a citywide tactical alert, which means all officers must stay on duty and can not go home at the end of their shift.

President Donald Trump also doubled down, saying he has instructed ICE and Border Patrol agents to be forceful in their protection of federal government property.

A dispersal order has been issued, and unlawful assembly has been declared in downtown Los Angeles in the area of Commercial Street and Alameda Street.

According to Los Angeles police, demonstrators began throwing bottles, rocks and industrial-sized fireworks at federal agents in the area, and tear gas was deployed into the crowd.

Police warned that anyone who does not leave the area will be subject to arrest.

Eyewitness News crews on the ground said the peaceful anti-ICE protest earlier in the day ended, and the crowd left before a smaller group of demonstrators began to face off with law enforcement.

AIR7 flew over the scene and saw a handful of protesters in the street in the area shortly before 9:30 p.m. Fireworks were seen going off.
