The seven people were airlifted to safety after the Santa Ana River swelled with rushing rain water.

CBS2’s Stacey Butler said none of the people rescued was seriously hurt.

Raging river waters swept several people into the wash near Riverside Avenue and Key Street, authorities said. Five agencies were involved in the rescue, Butler reported.
