A YouTube video has revealed that the three pitch invasions during Tottenham's game against Partizan Belgrade were part of an internet prank to see which man could spend the longest on the White Hart Lane pitch.
The Trollstation channel released the video late last night under the title 'Pitch Invasion Challenge'; Spurs are now facing the prospect of Uefa sanctions.
All three men wore t-shirts bearing the name of headphone manufacturer BassBuds, who produce licensed Spurs merchandise.
The company has released a statement condemning the invasions, but Tottenham have removed all mentions of the brand from club channels and related stock from their shops while they investigate whether the company was involved.
On their Twitter page, Trollstation spoke about their intent to invade the pitch ahead of the match against Partizan Belgrade, that ended 1-0 to the home side.
The group have also appeared to threaten to repeat the stunt. After the match their account posted the message: 'The question is Emirates stadium or Stamford Bridge ?'
Speaking after the game, Spurs boss Mauricio Pochettino said he was concerned for his players' safety.
An official statement from the north London club apologised for the "totally unacceptable behaviour" and the trio now face bans from White Hart Lane.
"You never know maybe what can happen on the pitch, but the behaviour from these people was only to go in and to show I don't know who or what," the Spurs head coach said.
"I am very disappointed but I think all the club, our supporters, and all people that love the game of football too are because this is a very strange situation.
"It is very disappointing but it's important now that we are focused on the next game on Sunday and to be calm and focused on Sunday when we have a very tough game with Everton."
