CONEY ISLAND - A boy and his mother have been hospitalized after an accident on a Coney Island roller coaster.

Multiple witnesses tell News 12 Brooklyn that the boy was improperly seated on the Sea Serpent ride when, after the ride's first turn, he became dislodged from his restraint. His jeans apparently got caught in the ride, resulting in his leg being run over. 

The boy's mother tried to help free him from the ride, but chipped her tooth in the process.

Sources say fellow riders tried rocking back and forth to jar the boy loose, which eventually worked.

"Our inspectors have conducted an initial inspection on the ride involved in the incident and found no defects with the equipment," the Department of Buildings remarked in a statement. "The investigation is ongoing."

An off-duty EMS worker was on the scene, and immediately tended to the pair.

The boy was rushed to Bellevue Hospital. His mother was sent to an undisclosed hospital.
