The police arrested a Hong, 34, who robbed a convenience store after midnight, and then pretended to be a cashier for 40 minutes.
With the cashier locked in the backroom, Hong casually attended to customers, the police in Gangseo, south western Seoul said.
He robbed three other convenience stores in the area April 4-9, and took some 700,000 won and ran away.
Hong allegedly called the shift worker not to report, but that was the point where the police started the investigation.
At the time he was arrested, he was already listed as a fraud suspect.
From August last year until last February, he pretended to be a worker at a bank near Suwon and Bucheon, and lied that he would offer bank loan. He then asked for the commission fees, and took off with it.
Hong said that he was hiding in motels and steam rooms, and committed the crime as he needed the money for daily necessities.
