An orchestrated series of pitch invasions at Tottenham's White Hart Lane ground were carried out as an internet prank.
A video posted on Youtube shows three men talking about invading the pitch ahead of Spurs' Europa League tie against Partizan Belgrade.
The match was suspended after a third pitch invasion just before half-time.
Spurs apologised in a statement  for the "totally unacceptable behaviour", but face Uefa sanctions for the incident.

The video suggests that the stunt was a challenge to see which of the men could remain on the pitch for the longest time.
The men were all wearing T-shirts bearing the name of a headphone manufacturer.
The company condemned the invasions on Twitter,  but Tottenham have removed all mentions of the brand from club channels and related stock from their shops while they investigate.
