LITTLE RIVER, S.C. — Authorities reported that ten individuals sustained gunshot injuries during an altercation on a private boat hosting a holiday event Sunday night along the South Carolina coast.

The incident in Little River occurred around 9:30 p.m., leaving some victims critically injured but no fatalities, according to a statement by Horry County Police.

At least one person was taken to the hospital who was not hurt by gunfire, police said.

The shooting was near a dock from which a private charter boat offers cruises. As the boat remained docked, detectives are working to pinpoint the exact location where the fight and subsequent shooting took place, police said.

A flyer online advertised a party Sunday night with a DJ on a three-hour cruise ending at 9 p.m. A woman who answered a phone number on the flyer early Monday said she was distraught seeing her friends get shot but then said she didn’t want to talk any more and hung up.

Someone who answered the phone at the company that owns the boat said he didn’t want to talk to a reporter.

No arrests have been made as detectives continue to investigative, police said.

A North Myrtle Beach police officer responding to the shooting accidentally shot himself in the leg at a marina about 3 miles (5 kilometers) away and is in the hospital in stable condition, North Myrtle Beach spokeswoman Lauren Jessie said.

Little River is about 20 miles (32 kilometers) northeast of Myrtle Beach. The fishing village is known for its docks and marinas where fishing expeditions, a casino boat and several dolphin cruises leave daily.
