One of the books is alleged to have hit a car, leading to the felony crime of throwing an object onto the freeway with the intent to cause great bodily injury during an immigration protest.

When marchers crossed overpasses of U.S. 101, prosecutors say Martin Richard Torres, 42, climbed onto a freeway sign, vandalized it and threw books at traffic below.

For the second straight week demonstrators gathered in downtown Los Angeles police to protest the immigration policies recently instated by President Donald Trump. The Los Angeles Police Department said protesters had entered La Plaza en El Pueblo and urged other members of the public to use caution in the area as the "non-permitted" demonstration continued.

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.

Demonstrators gathered outside Los Angeles City Hall Wednesday as protests against the Trump administration's crackdown on immigration continued in LA for a fourth day.
