Mamoudou Gassama (born 1996) is a Malian-French citizen, living in France who, on 26 May 2018, climbed four storeys on the exterior of a block of flats in Paris in 30 seconds to save a four-year-old boy who was hanging from a balcony.
The child’s father had apparently left the boy unattended to go shopping, and was subsequently charged with leaving his son unsupervised.
