LOS ANGELES (AP) — Federal prosecutors say a 64-year-old Monrovia woman is accused of pepper-spraying a mail carrier in the face in a fit of road rage.

The U.S. Attorney’s office said Wednesday that witnesses reported Ruby Valenzuela shouted obscenities and racial epithets at the mail carrier after she claimed her postal vehicle cut her off at an intersection April 20.
