A Malian immigrant dubbed Spiderman for scaling four storeys to save a child dangling from a balcony in Paris will be made a French citizen after meeting with French President Emmanuel Macron this morning.

Mamoudou Gassama, 22, was hailed a hero for single-handedly hauling the four-year-old to safety after scaling the facade of an apartment block in the capital's 18th arrondissement.

The dramatic rescue, which saw Gassama clamber from balcony to balcony and reaching the child in less than 30 seconds, was captured on video and widely shared on social media. He has since been compared to the Marvel superhero Spiderman.

Gassama, who said he arrived in France a few months ago 'dreaming of building his life' in the country, was pictured meeting French President Emmanuel Macron at the Elysee Palace this morning.

Macron said the migrant will be made a French citizen and will also be offered a place in the fire brigade.

Mamoudou Gassama (pictured today), 22, was hailed a hero for single-handedly scaling the facade of an apartment block in the capital's 18th arrondissement, and hauling the four-year-old to safety.

This is the incredible moment that Mamoudou Gassama scaled four storeys - using just his bare hands - to rescue a young boy dangling from a balcony in Paris

The four-year-old was filmed hanging on for his life outside an apartment on Rue Marx-Dormoy on Saturday afternoon, having been apparently left home alone while his father was out shopping

"All the (Gassama's) documents will be put in order," Macron told the sporty 22-year-old who has become a national hero, referring to his immigration status.

In the meeting, live footage of which was carried on the president's Facebook page, Macron gave Gassama a medal for bravery.

Without a thought for his own safety, Gassama took just seconds to reach the child in a spectacular rescue captured on film and viewed millions of times on social networks.

"I was not thinking of anything. I went straight up", Gassama, who wore jeans and a short-sleeved patterned shirt, told Macron, recounting the episode.

"Bravo," Macron replied.

"I'm pleased because it's the first time I've received a trophy like that," Gassama, who arrived in France in September 2017 and lives in a hostel for immigrants, said after receiving his medal.

The incident took place at around 8pm on Saturday in northern Paris.

Film of the rescue shows Gassama pulling himself up from balcony to balcony with his bare hands as a man on the fourth floor tries to hold on to the child by leaning across from a neighbouring balcony.

On reaching the fourth floor Gassama puts one leg over the balcony before reaching out with his right arm and grabbing the child. Firefighters arrived at the scene to find the child had already been rescued.

One witness told Le Parisien: 'There is a fence and a gap between them... The neighbour could not afford to lean back to get the child himself.'

The only injury sustained by the child was a torn nail. Gassama suffered a few scratches. An investigation into the incident is now underway.

Asked why he took such a risk to save the boy, Gassama (above) told Le Parisien: 'I did it because it's a child'

'Luckily, there was someone who was physically fit and who had the courage to go and get the child,' a fire service spokesman told AFP.

Paris mayor Anne Hidalgo praised the young migrant on Twitter for his 'act of bravery' as well as phoning him personally to 'thank him warmly'.

'He explained to me that he had arrived from Mali a few months ago dreaming of building his life here.

'I told him that his heroic act is an example to all citizens and that the city of Paris will obviously be very keen to support him in his efforts to settle in France,' she added.

After effortlessly making his ascent, encouraged by a crowd of onlookers, Gassama, originally from Mali, grabbed the boy and took him to safety

Tracked down by reporters 24 hours after the heroic rescue, Gassama said he had acted without thinking.

'I saw all these people shouting, and cars sounding their horns. I climbed up like that and, thank God, I saved the child,' he said.

'I felt afraid when I saved the child... (when) we went into the living room, I started to shake, I could hardly stand up, I had to sit down,' he added.

According to initial inquiries by the authorities, the child's parents were not at home at the time.

The father was later held for questioning by police for having left his child unattended and was due in court later, a judicial source said. The child's mother was not in Paris at the time.

Gassama's story instantly drew comparisons with that of another Malian migrant who was feted as a hero, and given citizenship, for helping save lives during a January 2015 terror attack.

Lassana Bathily helped hide hostages in the freezer during an Islamist jihadi attack on a Jewish supermarket, in which four people were killed.
