Authorities in China have released 10 staff members of Australian casino operator Crown Resorts on Wednesday, less than a year after they were arrested for promoting gambling in the Asian country.

Four employees, including Australian nationals Jerry Xuan and Pan Dan, were the first to emerge from a Shanghai detention facility, Reuters reported.

The report also quoted a man who identified himself as a lawyer for the detainees’ families—but declined to give his name—saying that Chinese authorities also released six other Crown staffers from a second facility in Shanghai.

With this, only six Crown-affiliated staffers remain in Chinese authorities’ custody, including Jason O’Connor, who is expected to be freed in August.
