“The shark was spotted swimming in between boats and came very close to the shore, swimming past tourists in just a few feet of water.”
The first shark attack to take place in the UK was in Sussex in 1785 on Brighton beach.
This latest incident is the first shark attack recorded since 2018 when a windsurfer was attacked in Felixstowe, Suffolk.
