Tennis doubles specialist Patrick McEnroe recently reminded fans of the disappearance of retired tennis star Peng Shuai after she made some sexual assault charges.Shuai, a tennis player from China, was a force to be reckoned with on the courts. She is a three-time Olympian who has amassed 25 tour titles over the course of her career. Her ground-breaking success has aided in raising the profile of women's tennis in China. However, last November, the 35-year-old disappeared.After publicly accusing a former Chinese Communist official of sexual assault back in November 2021, she disappeared. Shuai said in a post on the Chinese social media platform Weibo that former Vice Premier Zhang Gaoli forced her to have sex with him. The post was promptly removed from the internet.However, she later recanted her claims in a carefully crafted interview with French sports magazine L'Equipe in February 2022, announcing that she was leaving competitive tennis. Following the incident, the WTA suspended all of its tournaments in China and Hong Kong, and Shuai has not been seen in public since.In light of this, tennis icon John McEnroe's brother Patrick McEnroe used social media to remind followers about the Chinese player's allegations and raise questions about her whereabouts."A year ago today…Peng Shuai posted that she had been sexually assaulted.
