The BBC is today investigating how a serial prankster walked on to Gary Lineker's Match of the Day set and planted a phone playing porn noises he then set off during a live broadcast watched by millions last night.
In a major security breach, Youtuber Daniel Jarvis managed to get into Wolverhampton Wanderers' Molineux stadium and tape the mobile to some furniture.
Jarvis, from Gravesend, Kent, then called the phone from his home, playing high-volume moaning as Lineker introduced the live FA Cup match between Wolverhampton Wanderers and Liverpool.
