A local bank in southern Seoul was robbed by a man who threatened customers and workers there with “a gun-like object,” police said Monday.

A man, who is assumed to be in his 30s, robbed about 24 million won ($21,000) from a branch of the Korean Federation of Community Credit Cooperatives in Seocho-gu, southern Seoul, at around noon, the authorities said.

The suspect, covering his face with a helmet, took a male customer hostage and threatened a teller to hand him money. He then put the money in his bag and left the scene within five minutes before the arrival of police, they said. No causalities were reported.

The concerned bank reportedly did not have security guards.

The suspect then headed to Sinsa Station on Line No. 3 on a motorcycle with an engine of 100 cubic centimeters.

“The robber seemed to have closely planned the crime as he had concealed the motorcycle’s license plate,” the police said. 

The police were chasing the suspect and analyzing the surveillance camera footage as of Monday afternoon.
