Police are hunting a woman who rode a motorcycle while wearing only a bikini in South Korea.

The thong-wearing lady and her shirtless male companion were filmed roaming around the Gangnam district of the capital Seoul on July 31.

Seoul Gangnam Police Station officers said on Tuesday that they are currently investigating the incident.

Shocking footage shows the model and her driver speeding along the road while greeting locals stunned at their inappropriate outfits. The pair were both wearing helmets, but bizarrely, left most of their bodies exposed to the cold rain and air.

The man, estimated to be between 20 to 30 years old, was identified as a YouTube vlogger named 'Boss J'.

He told local media, claiming he merely wanted to show viewers how much he loves riding his motorcycle. He also said they were driving at around 20 to 30 kph when the viral videos were recorded.

Meanwhile, the woman who calls herself 'Green' is also an influence who posts provocative photos of herself wearing skimpy shirts and shorts.

Officials said they are considering filing charges against the two under South Korea's Minor Offenses Act for inappropriately exposing themselves.
