The arrangement: She was to be his social escort over three days in Singapore, allegedly for $38,000.
The Singaporean, 35, was said to have booked the Hong Kong-based woman.
In the end, their "social" arrangement ended in a brawl, after which the man was hospitalised, the woman was injured, and an ambulance had to be called to the scene.
The pair are disputing each other's version of events. The escort, Ms Di Di, claimed she flew here last week, spent two nights in a hotel with the Singaporean man, who only wanted to be known as Mr Yew, before he disappeared without paying her.
Mr Yew, however, claimed that Ms Di Di was trying to extort money from him.
