Public warned to stay out of water after shark spotted in Cornish harbour

The public has been warned to stay out of the water - after a massive SHARK was spotted swimming in a harbour. The 9ft beast was filmed close to the shore at the popular Cornish holiday hotspot of St Ives - and is thought to be either injured or lost its bearings chasing prey. Experts believe from footage submitted to them it is a blue shark and have warned the public to keep its distance while it remains in the area.
