Australia' top casino operator Crown Resorts said on Sunday that one of 18 staff arrested in China in October for suspected "gambling crimes" had been released from detention. Crown gave no more details.

The detention of 18 Crown staff, three of whom are Australian nationals including its head of international VIP gambling, has sparked concern about the impact on Australian casinos which rely on wealthy Chinese gamblers.

The Australian Financial Review reported that Jenny Jiang, who worked in administration for the gaming company in Shanghai, was released on bail on Thursday.

Analysts have linked the detentions to Chinese laws banning casinos from advertising or promoting gambling in the Chinese mainland, such as offering credit to high-spending clients.

In October, Crown said "less than half" its international VIP revenue, or about 12 percent of total revenue, came from Chinese high-rollers.

Australia's No. 2 casino company Star Entertainment Group warned of uncertainty around future revenue from China following the Crown arrests.
