A shark sighting off the waters of Marshfield, Massachusetts, led officials to temporarily close a four-mile stretch of beach Wednesday afternoon, police told NBC News. Officers called beachgoers out of the water, and they continued to monitor the shoreline after 2 p.m. ET for any sign of the shark. The beach was reopened about an hour later, police said.
The heightened precaution comes two days after a great white was spotted just 75 yards off the beaches of Duxbury, south of Marshfield. That shark was estimated at 12 to 14 feet long, and caused fear — but no injuries — before slipping back out to sea. At least four other great whites have been seen off the coast of Cape Cod this month.
