Federal immigration officers have detained 2,792 undocumented immigrants in the Los Angeles area since June, according to the U.S. Department of Homeland Security. Officials didn’t specify in which counties or cities the arrests occurred.

Nearly 3,000 people have been arrested since the beginning of June, more than three times the number in previous months this year.

Civil rights groups alleged that ICE and Border Patrol agents are rounding people up based on their race, and denying them access to lawyers. A federal judge said there's evidence what they're doing is illegal.
