A driver killed 35 people and severely injured another 43 when he rammed his car into people exercising at a sports centre in the southern Chinese city of Zhuhai, police said on Tuesday.

Police had detained a 62-year-old man at the sports centre in Zhuhai after the ramming late on Monday, on the eve of an airshow by the People’s Liberation Army that is hosted annually in the city.

Police identified the man only by his family name of Fan, as is usual with the Chinese authorities. Fan was discovered in the car with a knife, with wounds to his neck thought to be self-inflicted, according to the statement. Police said he was unconscious and receiving medical care. They added that their preliminary investigation suggested he had been dissatisfied with the split of financial assets in his divorce.
