The frantic 911 call from the mother of the child who fell into the gorilla enclosure at the Cincinnati Zoo was released.

“Hi. My son fell in the zoo at the gorillas,” the panicked mom told the dispatcher.

The call was released as the police investigate the boy's parents.

Reporter Mike Schell told On the Record he was informed that the county prosecutor would decide whether Child Services should get involved.

Schell said people can expect changes to the gorilla exhibit in the future.
