Footage has emerge of how a protester pretending to be a disabled football fan jumped out of his wheelchair and ran on to the pitch during the World Cup clash between Belgium and the USA.

The YouTube video raises questions about security at the World Cup, with the man able to run around the field shaking hands with players before he is finally escorted away by stadium staff.

He was protesting conditions in Brazil’s notorious favelas.

Scroll down to watch the full video.

The whole incident begins with the man leaping out of his chair, where he is sat with other disabled fans at the Arena Fonte Nova in Salvador, Brazil.

Quite clearly not disabled, he easily steps through the wire fence in front of the prime viewing section.

Wearing a Superman T-shirt, he then jumps down to pitch level, unchallaneged.

He then proceeds to run around the field of play, his shirt featuring the words ‘Save Favelas children’.

He manages to offer a handshake to Eden Hazard, the Belgium star who plays for English club Chelsea...

... and is pointed on his way by Kevin de Bruyne, who scored the crucial opening goal in the exciting encounter...

... before finally being led away by stadium staff.

Should the man have been allowed to get so near to the players without being challenged? Do you agree with his way of trying to get a message across? How do you go about checking if people have the disabilities they save they have? Let us know on the comment form below.
