GREENUP, Ky. - It should be the first rule in the robber's handbook: Don't hold up the place if the attendant knows you and you aren't wearing a mask, you will surely get caught.

Richard Riffe, 18, of 85 Township Road 155E is behind bars in Greenup, Ky., this morning, charged with the hold-up of the Rich Oil station at Third and Monroe streets in Ironton early this morning.

"We got the call at 4:01 a.m. a man came into the store with a knife and threatened the employee," said Ironton police detective Jim Akers. "He left with an undetermined amount of money."

Akers said the employee recognized Riffe and called police. Riffe was not wearing a mask at the time of the alleged hold up.

Riffe was apprehended in Raceland, Ky. less than an hour later.

"Apparently he had gone over there and was causing some problems. They have charges on him, too," Akers said.

Riffe was taken to the Greenup County Jail on three Kentucky charges: violating an emergency protective order, alcohol intoxication and resisting arrest. Akers said he will pursue a charge of aggravated armed robbery against Riffe as well.

Authorities said Riffe had gotten out of juvenile custody within the last year.

He will appear today before Judge Robert Conley in Greenup County District Court.
