Police say the girl climbed onto the windowsill of a first-floor flat, fell four meters and landed on a fence. The child was injured.
On Sunday, an attentive motorist noticed how the girl was clinging to the windowsill with her last efforts. The 41-year-old sprinted to the house in Linz and arrived in time to receive the child.
The 34-year-old mother, who was in the house at the time of the incident, was not aware of anything.
