FREDERICK COUNTY, Md. -- Frederick County sheriff's deputies are looking for a man who attacked a convenience store clerk with a banana.

A man walked into a 7-Eleven store in Monrovia just after midnight on Wednesday and demanded money.

Investigators said that when the clerk refused, the man became so agitated that he started grabbing items off the counter.

He snatched up a banana and began hitting the clerk, the sheriff's office said.

The clerk pulled out a knife, and the man with the banana split.
