Police officers have been involved in some of the most notorious cases in Hong Kong’s history.
On Monday, a video emerged of an officer fatally shooting a protester in the street, just hours after the British government lifted the ban on wearing face coverings in Hong, the birthplace of China’s one-party communist regime.
It was not clear if the man had been charged in the shooting.
In Hong Kong, where the government has imposed a five-day lockdown, a man with a black scarf wrapped around his face was found dead in his apartment on Saturday.
On Wednesday, a Hong Kong businessman who was shot dead in a shopping mall in a city near Hong Kong was found alive in the mall’s basement.
A Hong Kong policeman shot and killed a man wearing a mask and carrying a bag in the city’s Mong Kok neighborhood on Sunday.
The man was not arrested, but he was arrested on suspicion of trespassing and obstructing police.
The killing in Mong Kok came days after the arrest of another man in the same neighborhood who police said was wearing a black mask and holding a bag.
Authorities said Sunday they had opened an investigation into the killing of the man, and a spokesman for the Hong Kong police said it was still investigating whether he had been involved with protests.
Simons, who was born in Australia and lived in the United States for more than a decade, was shot on her way home from a shopping spree at a shopping center in central Hong Kong on Saturday night.
She was rushed to a hospital, where she died.
She had been taken to the police station by a member of the public, and police are still investigating.
A photo of Simons was posted on social media and showed her with two bullet wounds to her upper body.
Her death was the latest in a string of killings of police officers.
In 2011, the Hongkong government revoked the right to wear face coverers in public, which allowed citizens to wear a mask but not conceal their identities.
Police were told they could be arrested if they wore the mask while on duty.
The government also banned the wearing of face covers in public spaces, including parks, sidewalks and the streets.
In 2012, a Beijing man was charged with shooting and killing a policeman in Hong Kowloon after the officer fired his service weapon at him, killing him.
