Officials detained about 200 demonstrators after dispersal orders Monday night, but issued warnings and released them.

The large group, calling for a National Day of Action, could be seen through aerial footage walking in the middle of Spring Street, moving along to block an intersection at Chick Hearn Court and 11th Street all the while waving Mexico flags and carrying protest signs.

Draped in Mexican and Salvadoran flags, roughly 1,000 demonstrators gathered near City Hall shortly before noon, blocking traffic at Spring and Temple streets.
