Long Beach police say one person died after a call came in for swimmers in distress Sunday morning.

Lifeguards pulled three men from the water due to powerful rip currents. Police say one of the men went into cardiac arrest and was pronounced dead at the hospital. They say he was 31 years old and from Nassau County.

John Skudin is the lifeguard supervisor for the City of Long Beach. He says the emergency call came in around 8 a.m., an hour before lifeguards were scheduled to be on duty.

Luckily, he says some lifeguards just happened to be there early.

"Water kills and unfortunately again this morning, again when we were not on duty, they went in," he says. "People are swimming when lifeguards are not on duty. So, there's your first rule, you should never swim when a lifeguard is not on duty."

This is second drowning in the last several days in Long Beach. Police say an 18-year-old man drowned and several of his friends had to be rescued and taken to the hospital Friday.

Skudin says the beach was not open to swimming both Saturday and Sunday because of rough currents.

In his 47 years of being a lifeguard, Skudin says the best advice for those caught in rip currents is to swim parallel to the beach.
