A police chief in the western autonomous region of Xinjiang was sacked days after he was accused online of keeping twin sisters from a dancing troupe as mistresses.
The removal of Qi Fang as head of the Public Security Bureau in Usu on Saturday came after the nation's new leadership vowed last month to implement tougher anti-graft measures, Xinhua reported, citing an unnamed source from the Tacheng government, which administers Usu.
The post on December 3 on news portal Iyaxin.com  had been widely circulated. It said the twins, 31, were employed at the bureau five months after Qi was promoted to police chief in June last year. One of the women was made vice-captain of special operations, while the other was made an assistant police officer in the traffic department.
It was unclear whether either had any previous work experience with the police.
The post also alleged that Qi was renting a luxury apartment in the city's high-end area, paid for by the bureau.
"An initial investigation … found that what internet users claimed was partially true," Tacheng officials told Xinhua. "The investigation is ongoing."
Qi is the latest high-ranking official accused online of corruption in the past month to be promptly investigated.
On Wednesday, Lanzhou Mayor Yuan Zhanting was accused of owning at least five luxury watches. Gansu disciplinary inspectors told People's Daily that his most expensive watch cost 25,100 yuan (HK$30,900) and the accusation he had worn other luxury watches "lacked substantial evidence".
On Friday, the police chief of Taiyuan, Shanxi, was suspended and placed under investigation a day after a video circulated showing his drunken son, who is also a policeman, attacking a colleague after being caught drink-driving, Xinhua reported. The son was reportedly escorted home by a senior officer and traffic police were allegedly told to cover up the incident. However, the officer who was attacked refused to stay silent.
Last month, the Shandong Provincial Commission for Discipline Inspection put a deputy head of the local agricultural department under investigation after a note he allegedly wrote to his mistress was leaked online. It said Shan Zengde would divorce his wife.
