A man in a "Jesus Saved My Life" hoodie knocked an Oklahoma store clerk unconscious when the victim carded him for a cigar sale, according to police.

"Guys, this one will make you mad," the Oklahoma City Police wrote in a Facebook post showing a surveillance video of the incident.

Police say two people walked into the store and became upset when the clerk asked for ID before he would sell them a cigar.

The man in the hoodie was seen on the video walking behind the counter and attacking the clerk until he crumpled to the ground.

The video then showed the two suspects running out of the store.

Police say video of the incident was "extremely clear" and asked anyone with information on the suspects to call Crime Stoppers with anonymous tips. They say there is also a cash reward possible in the case.

The surveillance video, dated March 5, was posted by police on Wednesday.

Information about the clerk's condition was not released.
