Multiple shark attacks reported off New York shores; 50 sharks spotted at one beach

Two swimmers were apparently attacked by sharks off the shores of Long Island on Tuesday, a day after two others reported being attacked while enjoying the water at popular New York beaches.

At least one beach delayed opening to holiday revelers Tuesday, after officials said drones spotted some 50 sand sharks that morning near a popular beach park. When the beach reopened, swimmers were advised to stay close to shore.

"This morning, prior to lifeguards going on duty and our authorizing swimming, we had a complete drone patrol. And right here in front of Field 3, we saw a school of sharks. There were approximately 50 sand sharks there," Charles Gorman, New York State Parks Regional Director, told CBS New York.
