Two Suffolk County beaches reopened to swimmers this morning after a lifeguard was attacked by a shark Sunday.

The attack happened at Smith Point Beach.

A lifeguard participating in a safety exercise at Smith Point beach was bitten by a shark, Suffolk County Executive Steve Bellone said.

According to Bellone, the lifeguard was playing the role of a victim in the water during a riptide drill when he became a true-life victim.

He said that Zack Gallo was bitten in the chest and sustained an injury to his hand. He was able to walk out of the water after calling out for help.

Gallo was then bandaged and taken to Southside Hospital for treatment. He has been a lifeguard for 10 years and is doing well, Bellone said.

In response to what happened to Gallo and the sighting of a possible second shark, swimming was halted and both Smith Point and nearby Cupsogue Beach were closed for the day.

Both beaches reopened to swimmers Monday at 10 a.m.
