A newborn girl miraculously survived after being buried alive for seven hours, Brazilian police said.
A 15-year-old gave birth earlier in the week, but believed the baby had died and buried her in the back garden of the family's house, officers in the central state of Mato Grosso said.
Police received an anonymous tip related to the burial and dug up the baby, who was hospitalised and said to be in stable condition.
The baby's grandmother and great-grandmother have been taken into custody pending an investigation.
Police questioned the 15-year-old mother and released her after a few hours.
