A storm chaser in Texas was attacked by a man with a knife who had apparently faked an injury along a roadway, Trace Gallagher reported on "The Kelly File."

Jeff Piotrowski, a prominent storm chaser for the last 35 years, was broadcasting live online on Saturday when the terrifying attack occurred. 

As you can see on the video, Piotrowski was driving along the road when he spotted a man who appeared to be holding his head.

When he stopped to see if the man was OK, the man suddenly pulled out a knife and lunged at him. 

Piotrowksi said the man then hung onto his truck as he quickly drove away. 

He then found a deputy and the suspect was arrested on charges of assault and possession of a controlled substance.
