The Malian migrant, who rose to fame after scaling four apartment storeys to rescue a boy hanging from a balcony, has started his first day with the Paris fire brigade.

Mamoudou Gassama was nicknamed ‘spiderman’ after footage of him athletically climbing the flats to reach the boy was viewed millions of times on social media.

The feat secured the 22-year-old an audience with President Emmanuel Macron, who granted Mr Gassama French citizenship.

The Paris fire brigade also offered Mr Gassama a job in the wake of his heroics, an offer the service made good on when the Malian joined its latest intake of recruits over the weekend.

The fire service tweeted a picture of its new volunteers saying: “24 new volunteers civic service including Mamoudou Gassama joined this afternoon the fire brigade of Paris. Congratulations to them.”
