4 year old falls off building but is saved by her dress

This could've been tragic. A video from Thailand shows the rescue of a four-year-old girl. She had fallen off the roof of a hospital, but was saved because her dress snagged on the building's sign . . . and then someone pulled her up.

The clip starts while she's hanging from the sign and you see a person on the roof reach over the side to grab her arm. The rescuer was being held by other people on the roof.

The whole thing started when she wandered away from her father who was being treated for something. She walked through a fire escape door, went up the stairs to the roof . . . and then started chasing a lizard until she fell off the side.
