Investigators are asking for help finding the man who robbed a credit union Thursday afternoon.
The FBI says it knows who the suspect is, but not where he is.
They say 29-year-old Jonathan Key walked into the Knoxville Post Office Credit Union on Clinton Highway around 1:30 p.m.
He handed the teller a note saying he had a weapon, and demanding money. The teller handed him money and he fled.
If you know where authorities can find Key, you're asked to call the FBI at (865) 544-0751.
