An elderly store clerk is brutally attacked and the whole think is caught on tape.
Now Indiana police are asking for your help and we warn you the video is disturbing.
It happened Saturday night at a Fort Wayne GNC store and when you watch the video, the attacker can be seen in the background, punching a 77-year old employee.
The victim is then dragged to the back of the store and threatened at knifepoint.
"Obviously the perpetrator, much younger, physically stronger, could have demanded the money and it would have been over with, very brutal. That's why we want to put this compelling video in front of everybody," says Mike Joyner of the Fort Wayne Police Department.
The robber escaped with cash and two telephones while the elderly suffered bruises to his eye and head but luckily, his injuries were not serious.
