Video captures terrifying scene in Florida pool

HIALEAH, FL (KTRK) -- A frightening scene unfolded in Florida. Surveillance video captured the moment when three children were shocked while in a swimming pool

In the video, you can see the moment a girl touches the rail. Her head jerks back and she freezes, her muscles paralyzed by the electricity.

A dark patch in the water is another child also unable to move. Luckily, nearby adults pulled all the kids out.

In all, three children were hospitalized. City inspectors say a pool pump was not put in properly and malfunctioned.
