Brazilian TV has broadcast footage of a baby girl being rescued from a black plastic bag floating in a lake.
Amateur footage captured the moment when the bag was fished out and opened by a park worker in Belo Horizonte.
Jose da Cruz, who was filmed performing the rescue, said he was first alerted to the bag by sounds of a "cat crying".
The baby, thought to be two months old, is said to be healthy, and is being kept in hospital while authorities search for relatives.
"I heard a sound of a cat," Mr da Cruz told television channel TV Globo. "But, between a child and a cat, the noise is the same.
"Then, the noise was increasing and it caught my attention."
Mr da Cruz said he then called security and a local cameraman, who happened to be filming in the area, filmed the baby being pulled out.
Eyewitnesses said that the plastic bag was floating attached to a piece of wood in the Pampulha Lagoon, one of the city's main parks.
