Another Charleston carriage horse bolted Thursday, taking another group of people on a Mr. Toad's Wild Ride through the streets.

Jessica Buchanan was inside her house at 150 Tradd St. about 3:30 p.m. when she heard what sounded like galloping coming toward her house. Then she heard a loud thud, and the whole house shook.

She ran outside to see a carriage up against the side of her house. Two of the five passengers were on the ground.

She went back inside to get some wet towels. The horse was scratched up and a passenger received a bump on the leg, police said.

The carriage gouged the wood siding on the house and tore off two shutters.

Several neighbors stopped by to complain about the parade of carriages along Charleston's historic streets, and Buchanan agreed.

"The town is so crowded, and it's too hot," she said. "It's amazing that people don't get killed. I'm just glad nobody went through the window."

Police said the carriage belonged to Charleston Carriage Works. Employees at the office on Anson Street said nobody who could talk about the crash was around.

Police were trying to determine what caused the horse to bolt, spokesman Charles Francis said.

The horse ran down Limehouse Street, tried to turn the corner, and ran into the house on Tradd Street, he said. Gouge marks were visible in the street at the corner.

It was not immediately known how often carriage horses bolt in Charleston.

On April 22, a horse pulling a carriage took off running with three passengers in tow down Anson Street before crashing into the City Market. No one was injured, although video released by the police department shows the passengers clinging to their seats. It was not known what caused the horse to take off running.

In January 2008, a carriage horse bolted on South Battery. The horse took off running after the carriage hit a curb and overturned. Six of the 13 passengers were taken to hospitals for treatment and released the same day.
