A German tourist swimming off a Hawaii beach has lost an arm in a shark attack.
Hawaii media report the woman, who was in her 20s, was taken to a hospital in critical condition after she was attacked Wednesday afternoon. The Honolulu Star-Tribune reports her right arm appeared to have been severed below the shoulder.
Two of her friends and a kayaker helped her to shore.
Helicopters were sent over the coastline to check for the shark, according to the newspaper.
