On Friday, United States Immigration and Customs Enforcement (ICE) agents took dozens of people into custody during raids across Los Angeles city.

Caravans of unmarked military-style vehicles and vans loaded with uniformed federal agents streamed through the city as part of the operation. The ICE agents raided several locations, including an apparel store in the city’s Fashion District, a Home Depot in Westlake District, and a clothing warehouse in South Los Angeles, according to the Los Angeles City News Service.

In response, crowds of demonstrators protesting the raids massed outside a jail where some of the detainees were believed to be held and spray-painted anti-ICE slogans on the walls of the Edward R. Roybal Federal Building in downtown Los Angeles. Los Angeles Police Department (LAPD) officers – who did not take part in the immigration raids – were called in to quell the unrest. Wielding batons and tear gas rifles, LAPD officers faced off with the demonstrators after authorities ordered them to disperse on Friday night.

Some protesters hurled broken concrete towards the LAPD officers, the Reuters news agency reports. Police responded by firing volleys of tear gas and pepper spray. LAPD spokesperson Drake Madison said police on the scene declared the gathering an unlawful assembly, meaning that those who failed to leave the area were subject to arrest, according to Reuters. It’s not immediately clear how many arrests have been made. Los Angeles Mayor Karen Bass condemned the federal immigration raids, saying they “sow terror in our communities and disrupt basic principles of safety in our city”.

Caleb Soto, of the National Day Laborer Organizing Network, told Al Jazeera that between 70 and 80 people had been detained, but only three lawyers have been allowed access to the detention centre where they were being held to provide legal advice. “The chaotic manner of the raids that we saw today happening throughout Los Angeles and different day-labour worksites and garment worker work sites was an example of the purpose of what this Trump administration has set out to do, which is to create as much fear as possible,” Soto told Al Jazeera.
