Suggestions that the child had been dumped have been revised after it emerged that the 22-year-old unmarried mother of the baby was the one who raised the alarm.

According to a police source in Jinhua, in the eastern province of Zhejiang, the woman gave birth unexpectedly when she went to the lavatory on Saturday, and the newborn fell into the squat toilet.

The mother, who had hidden her pregnancy, telephoned her landlord, claiming she heard “weird noises” in the pipe, and the proprietor called police after spotting the infant.
