HONG KONG —

A man walking to work was beaned by a falling turtle, according to news reports today.

A freshwater turtle weighing more than two pounds struck 36-year-old Lui Wai-kwong on the head, bruising Lui’s temple and badly injuring the turtle, the accounts said. The tortoise plummeted from a high-rise residential building.

Passerby struck in the head by turtle that fell out of Hong Kong apartment window

Hongkongers traditionally believe that turtles are a symbol of good luck, but if you were unsuspectingly hit in the head by one, you would be forgiven for thinking otherwise.

A 29-year-old man walking near a housing estate in Kwai Chung Tuesday evening was struck by a turtle falling from a window, causing injuries to his head. The 29-year-old, surnamed Feng, was conscious and called the police. He was sent to Princess Margaret Hospital for treatment, HK01 reported

The turtle, found bleeding and with a cracked shell at Kwai Hing Estate, did not survive. Its carcass was taken away by the Society for the Prevention of Cruelty to Animals (SPCA) for examination.

Before the incident, the turtle was kept in a terrarium on the windowsill. It is believed to have climbed out of the open window and fallen to the ground.

The turtle owner, a 56-year-old man surnamed Hui, was arrested on suspicion of animal cruelty.

If found guilty, he could face a maximum fine of HK$200,000 (US$25,760) and three years’ imprisonment. He was released on bail Wednesday, according to the police.

According to local media, a five-foot-long turtle smashed into a man’s vehicle traveling along Queen’s Road West in Sai Wan in 2015, shattering the car’s windshield into pieces. The driver survived the bizarre incident without injury, and the turtle, suffering a scratched shell, was taken away for further examination.

these are probably not all freak accidents; I have also read of problems in Hong Kong with people tossing all sorts of things, including live animals, out of tall buildings.
