Dozens of people were arrested Friday in multiple immigration enforcement operations involving Homeland Security Investigations, the DEA and the FBI that took place across Los Angeles. The arrests prompted citywide protests.

A local immigrant rights organization said more than 45 people were detained in the operations, which were described as “random sweeps.”
