Two men attacked a Papa John's delivery driver Saturday night, shooting him with a shotgun as he fled, according to a Des Moines police report.

An officer was dispatched to 37th Street and University Avenue in Des Moines about 11:30 p.m. after callers reported hearing a loud "boom" and a man yelling for help.

When the officer arrived on the scene, he reported finding the man laying on his side with numerous small bullet wounds in his thigh and buttocks.

The victim said he was walking to the door of a home to deliver pizza when he was approached by two men wearing face masks. One of the men swung at the victim but missed, and the men fought briefly before the victim began to run away. He reported falling to the ground after being shot and turning to see one of the men holding a shotgun. The officer reported the man's wounds appeared to be caused by a shotgun blast of birdshot.

The men stole about $20 worth of pizza, and it was not immediately clear whether they were successful in stealing any money.

The victim was transported to Iowa Methodist Medical Center for treatment.
