On Wednesday, a great white shark was recorded from a drone circling in the waters very close to the shore of Cape Cod a few hours before a man was attacked in the same area.
The shark was seen about 14 hours local time, very near to several swimmers.
The 61-year-old man stood on the same 30-meter waterline at the same time that the shark bit him at about 4 pm local time.
After being bitten, he was treated by local emergency service on the beach and then flown by helicopter to the Tufts Medical Center in Boston.
The shark caused deep wounds to his torso and legs.
The species of the Shark is not defined.
