50 people arrested hours after hundreds gathered for another anti-ICE protest in DTLA

The Los Angeles police has issued a dispersal order near the downtown Los Angeles federal building after anti-ICE protesters clash with officers.

Los Angeles police have issued a dispersal order near the federal building as protesters face off with officers in downtown L.A. following Friday's "ICE Out" demonstration.

According to LAPD, all protesters in the area of Alameda between Union Station and 1st Street must leave or they will be arrested.

The dispersal order was issued around 5:45 p.m.

Spring Street between Temple and 1st Street is closed due to the demonstration.

Before the dispersal order was issued, AIR7 video showed demonstrators throwing debris toward officers near the federal detention center. Tear gas was eventually deployed, and the crowd began to move away from the building.

As a protest in downtown Los Angeles appeared to grow rowdy on Friday afternoon, the Los Angeles Police Department declared a citywide tactical alert.

It happened as protesters began to clash with officers outside the downtown L.A. federal detention center.

AIR7 video showed protesters throwing debris toward officers outside of the building.

A citywide tactical alert means all officers must stay on duty and can not go home at the end of their shift.

As thousands gather for a day of "ICE Out" protests across the country, including in downtown Los Angeles, AIR7 video captured the moment a group of protesters began to clash with federal agents outside the federal detention center.

It appeared some protesters were throwing items toward officers, getting closer and closer to a door at the back of the building.

The crowd eventually moved further back from the building as it appeared federal agents deployed tear gas and fired less-than-lethal ammunition toward the crowd.

Thousands of people converged in downtown Los Angeles on Friday afternoon as part of a national day of action protesting ongoing federal immigration operations.

The protest is part of the national "ICE Out" rally. Organizers of the movement are demanding that federal immigration agents leave their neighborhoods. The day of action also called for a "national strike," asking people to keep their children home from school, stay home from work and not buy anything.

The protest began outside City Hall before the protesters marched to East L.A.

It's just one of many protests around the country in response to two deadly shootings involving immigration agents who killed two U.S. citizens in Minnesota.
