The video shows the girl walking home from her school in Bradenton. The man chases her down, and grabs her from behind.
Investigators say he carried her to a wooded area to rape her, but he ran after she said people were nearby and watching.
Deputies think the same man is responsible for two other attacks on teenage girls. One managed to get away, but the other did not.
Children are being warned to stick together and be alert until the predator is caught.
