A man who allegedly threw a 2-year-old girl in a stroller to the ground leaving her critically injured after a dispute with the girl's mother has been criminally detained, Beijing police said.

Media reports said the man, sitting in the front passenger seat of a white car driven by a male companion, gestured to a woman to move away so that the car could be parked near a bus station in Beijing's Daxing district at around 8:50 pm on Tuesday.

The woman, who was checking her child in a stroller, refused to move.
