Police are hunting for so-called "G-string man," a man in his 20-30s who visited a coffee shop in Chungju wearing a G-string on July 17.

The investigation started after photos of the man ― wearing a black mask, a tight short-sleeved white shirt and a black G-string ― went viral online.

Police confirmed with CCTV footage that the man visited a coffee shop in the city's west about noon on July 17. Investigators said he walked in, queued, ordered a drink, sipped it and left. He didn't care about people's attention and did nothing wrong in the shop, they said.

Captured from CCTV footage.

"A man in a G-string came in, ordered a drink and paid normally," an investigator quoted a cafe employee as saying. "He left after drinking for a short time in the shop."

Police say they plan to check his mental state if he is caught.
