JAMES ISLAND -- A security guard's shotgun went off and struck a man in the hip during a disturbance early Saturday outside a nightclub, authorities said.

The Charleston County Sheriff's Office has not identified either man.

Deputies responded to a call of a disturbance and shooting at The Lake House on Mosquito Beach off Sol Legare Road about 3 a.m. when they discovered the victim and several security guards.

Brady said a large crowd had gathered earlier outside around a vehicle and a fight had broken out.

The security guards were clearing the crowd from the parking lot when "they heard what they identified as a gun being racked," Brady said.

One guard grabbed a shotgun loaded with non-lethal rounds and was bumped into, Brady said. The weapon fired and struck the victim, he said.

EMS transported the man to the hospital. His condition is not known, but Brady said the injury was not life-threatening.

He also said a male fled the area after firing off several rounds during the disturbance.

The Sheriff's Office continues to investigate the incident.
