Two New York beaches close after shark bites lifeguard

Zach Gallo was reportedly participating in a water training exercise when incident occurred on Long Island

Just when it was warm enough to go back in the water, Fourth of July revelers on a popular beach on New York's Long Island were ordered out again after a shark bit a lifeguard.

Zach Gallo was reportedly playing a victim in a water training exercise Sunday when a 4- to 5-ft-long shark bit him in his chest and right hand off Smith Point Beach, 70 miles east of Manhattan.
