Police in Savannah, Ga., were searching Sunday for a gunman who opened fire at a crowded fair, wounding seven people.

The shooting happened Saturday night at the Coastal Empire Fairgrounds on Savannah's suburban south side.

Savannah-Chatham metro police officers at the fair had just cleared up an apparently unrelated fight near the rides when shots were fired nearby at about 10:40 p.m., the Savannah Morning News reported.

Nobody was killed but seven people were treated for gunshot wounds at area hospitals, Savannah-Chatham County police spokesman Julian Miller said Sunday.

"The place was packed," Miller said, according to the AP. "It was Saturday night at the fair, and that's a big night."

Officers worked through the night to clear the scene and to search for a gunman reported to be wearing a dark jumpsuit.

The motive for the shootings was not known. Several people were detained and questioned Saturday night, but all had been released by investigators, according to AP.
