People at Imperial Beach Wednesday morning were advised to swim at their own risk after a 7 to 8-foot shark was spotted off the coast.
A Border Patrol helicopter first spotted the shark at around 9 a.m. in between IB and Silver Strand State Park, and a San Diego County Sheriff's Department helicopter spotted it again about an hour later, the City of Imperial Beach said.
Imperial Beach lifeguards on watercraft followed what appeared to be a Great White shark in the area before it swam into deeper water and never came back.
The city said the shark was seen further than a mile off the shoreline and did not display aggressive behavior. No shark advisory was issued.
