Boy hit, killed by roller coaster

ATLANTA, Georgia (CNN) - A teenager died Saturday after he was decapitated at the Six Flags Over Georgia theme park outside of Atlanta, authorities said.

The youth died after he scaled two 6-foot fences around the Batman roller coaster ride, said a statement issued by park spokeswoman Hela Sheth. He was struck by the coaster and killed, she said.

"We do not know why this person was intent on gaining access to this restricted area," the statement said, noting that multiple signs are posted stating, "Danger Zone," "Do Not Enter" and "Authorized Personnel Only."

"Some witnesses have stated that the individual was trying to retrieve something he had lost," Sheth said in the statement. "Others reported that he was trying to touch the ride. This is merely speculation at this point, and we are working with park visitors and local police to learn more."

No one on the ride was injured, she said.
