The Border Patrol says three people have been rescued while trying to cross the storm-swollen Tijuana River from Mexico.
Spokesman Daryl Reed says agents spotted about a dozen people who appeared to be illegal immigrants about a half-mile north of the border late Wednesday night.
He says three adults were swept away by the fast-moving current. Rescuers pulled them from the water and they were treated at a hospital for hypothermia.
Reed says a U.S. Coast Guard helicopter searched for several hours to make sure nobody else was carried away, ending the search before dawn Thursday. Nobody else was found.
Reed says a dozen people, including the three who were rescued, are in Border Patrol custody and may be sent back across the border.
