At first, Eto’o seems happy to pose for photos with waiting fans as he leaves the venue, before a man with a video camera approaches him to his right, Daily Mail reported.
The footage, filmed by La Opinión, apparently shows the couple exchanging words, before the video cuts out a few seconds later, and Eto’o returns to the scene to confront the man.
It is not clear what was said to irritate Eto’o, who is in Qatar in his role as a legacy ambassador for the 2022 World Cup, but he reacts furiously and starts shoving the cameraman.
At this point, several bystanders step in to try to quell the interruption, but Eto’o is determined to go after the man and eventually must stop him as he continues to try to confront him.
With four men holding Eto’o, footage shows him giving his phone to a man, before running out of the group to knee him in the face and knock him to the ground.
The brutal blow appears to occur as the man ducks, knocking him out as Eto’o returns to continue the confrontation.
Although understandably surprised, the unknown man is helped to his feet and does not appear to be seriously injured by the shocking blow, while Eto’o is again held back by two men.
As La Opinión reported, journalists quickly asked Eto’o what had happened, but he was “crazy” and security quickly took him away.
Their main concern in Qatar was clearly watching their nation Cameroon and how their tournament unfold, but they met with a disappointing finish with a group stage knockout, despite a win over Brazil.
Daily Mail has contacted Eto’o and the Cameroon Football Federation for comment.
Eto’o retired from playing in 2019, following a spell in Qatar with Qatar SC. He is most famous for his stints with Barcelona, Inter Milan and Chelsea, after coming through Real Madrid’s academy in 1997.
He also has 118 caps for his country, the second most of any player in history.
It is not the first time the 41-year-old has made headlines for non-footballing reasons in recent months, having received a 22-month suspended prison sentence in June for £3m tax fraud, failing to have declared the income from the transfer of image rights.
According to Sport, the former Barcelona and Inter Milan forward admitted the offense but alleges that he was the victim of manipulation by his former agent José María Mesalles.
The fraud refers to the fact that Eto’o did not declare the income derived from the transfer of image rights to Puma and Barcelona in his personal income tax return between 2006 and 2009.
