BEIJING -- Five suspects have been detained over a hotel attack incident in Beijing, local police announced on Saturday.

On last Sunday, a woman was throttled and pulled away by a man in a black leather coat in the hallway of a Yitel hotel in Beijing's eastern Chaoyang District. The incident was recorded by a surveillance camera and the footage began circulating online after a Weibo user nicknamed "Wanwan" posted it on her account on Tuesday.

The man in the footage, surnamed Li, 24, was caught on Thursday in Xuchang City in Henan Province, about 760 km from Beijing.

He confessed that he was handing out cards with prostitute information in the hotel when he saw the woman and thought she was of the same occupation and a competitor.

Li said he then contacted his gang and started to drag the woman to expel her away.

All five suspects involved in this case have been detained, according to police. Further investigation is under way.
