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.

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.

A man faces seven years in prison after he is accused of throwing books on the freeway.
