At least one person is confirmed dead and 11 injured in a shooting at a California food festival on Sunday, a hospital spokesperson said, amid reports that the casualty toll could be higher.

Joy Alexiou, a spokesperson for the Santa Clara Valley Medical Center, said she did not believe that the shooter was among those hurt.

A city councillor, Dion Bracco, earlier told The New York Times that three people were killed and 12 injured in the shooting on the last day of the Gilroy Garlic Festival, an annual three-day event south of San Jose. 

Bracco said one suspect was in custody.
