Taipei  - Police in southern Taiwan are looking for a man who rode his motorbike naked through a city's main streets for one hour, TV reports said Tuesday.

The man, aged between 30-40, rode a motorbike in Tainan City for about one hour on Monday in a light drizzle caused by typhoon Jangmi, cable TV channel TVBS and ETTV reported. He wore only a crash helmet.

Although a lot of people stayed home because of the typhoon, many saw him and took photos with their cell phone cameras, TVBS said.

TVBS broadcast a video clip which showed the man riding a motorbike and sometimes honking the horn.

Police suspect the man is an exhibitionist and plan to file charges of conducting an immoral act in public place against him, the TV reports said. (dpa)
