All Myanmar Youths
The woman surnamed Ye, 19, posted her room number at the hotel in Haitang Bay, China, on social media and it quickly began trending online.
The short geotagged post, under the username Qianjin Yeye on March 1, read: "Somebody come get me... Sex... for free... 6316."
A video was also shared showing the teenager wearing a bikini inside the room hotel.
According to police, the woman's posts on China's Twitter-like microblogging platform Sina Weibo and instant-messaging application WeChat caused numerous people to turn up at the hotel.
A number of people also called the front desk enquiring about the guest in room 6316, the official police statement added.
Unconfirmed social media rumours claimed some 3,000 people either asked about or showed up at the Hilton in response to the blogger's offer.
A subsequent post on WeChat showed the woman begging for people to "stop sharing" her offer, which she claimed was "just a joke".
The hotel called the police but when Haitang District authorities arrived at the Hilton at 10pm - two hours after she made her first post - the woman had already checked out and disappeared.
