SAN CLEMENTE, California -- Authorities say they have arrested 20 Mexican citizens at an Orange County beach after they tried to enter the United States illegally by boat.

The U.S. Border Patrol says the 17 men and three women were picked up after agents saw them come ashore at San Clemente State Beach around 3 a.m. Monday.

Authorities say a 36-year-old woman broke her leg after jumping from the boat and was taken to a hospital for treatment. The rest of the group was taken to a Border Patrol station for processing.
