(Yicai Global) July 19 -- Executives of Jiayuan.com, a well-known Chinese dating platform in which Fosun Pharmaceutical Group is a major shareholder, have been arrested after the drugmaker found evidence they had abused their positions to commit crimes and reported the matter to the police.

Fosun uncovered the irregularities during daily checks of the dating website, the Shanghai-based firm told Yicai Global today. It did not disclose details about the executives taken into custody, but online rumors yesterday said the chief executive officer and a number of vice presidents had disappeared.

Individual managers were cooperating with the judicial investigation for personal reasons, Fosun added.

Jiayuan.com belongs to Baihe Jiayuan Network Group whose CEO is 50-year-old Wu Linguang. He has been in charge of Jiayuan.com since joining the company in 2012, according to corporate information platform Aiqicha.

Jiayuan.com was founded in 2003 by Gong Haiyan, who stepped down as CEO in 2012 and left the company in 2015 after selling her entire stake. The platform debuted on the Nasdaq in May 2011, but was delisted after merging with rival Baihe.com in December 2015 and changed its name to Baihe Jiayuan.

In July 2018, Fosun Group, owned by renowned Shanghai businessman Guo Guangchang, announced that it had acquired a controlling stake in Baihe Jiayuan.

According to data recently disclosed by Fosun, total registered users of Baihe Jiayuan’s platforms exceeded 400 million at the end of April, with 11.1 million monthly active users. It also had more than 200 offline stores nationwide.
