The FINA Diving World Series was briefly interrupted on Sunday at the London Aquatics Centre when an unwelcome guest jumped off one of the diving boards.
A male spectator made his way through security and stripped down to his speedos while being chased by a guard.
However, security personnel did not catch him in time and the invader bounced off the board and into the pool as boos rang around the venue.
The incident occurred during the men's 10m platform final, which Great Britain's Tom Daley won with a score of 554.05.
