Video released by the Hialeah Police Department in Florida showed three children being shocked when the pool they were swimming in became electrified.
It happened last month at the Palm West Gardens apartments in Hialeah.
The video showed one girl touching the hand rail then suddenly freezing as she received a shock.
He father immediately pulled her out of the water.
Another girl could be seen grabbing the railing but she was unable to let go as the electricity contracted her muscles.
Her grandfather dragged her from the pool and also received a shock in the process.
Officials told CNN that the pool became electrified as a result of unconnected ground wires in the pool’s pump house.
