A crowd of immigrant rights advocates blocked a Homeland Security van late Thursday from accessing the Metropolitan Detention Center in downtown Los Angeles.

Video footage showed dozens of people standing in the street, in front of a marked van, chanting, "Drive out ICE!" and "Stop the deportations!" Some held signs.
