A helicopter unit with the Orange County Sheriff’s Department confirmed multiple sharks were swimming near the San Clemente coastline in California on Wednesday, May 10.

The sharks were first reported by a surfer, who reported the sharks were circling his board near San Onofre State Beach, according to reports. Multiple shark sightings were reported in San Clemente just after 2 pm Wednesday.

In this video, one shark was identified as being near 10-feet long, and deputies say there were people wading on the shore, but not swimming.
