The Rolling Stones singer was the target of an assassination attempt which only failed because the boat the would-be killers were using was swamped in a storm.



Details of the plot have been revealed by an FBI agent as part of a BBC series on the American crime fighting agency.



The attempt to kill Sir Mick was made by a group of Hells Angels after the infamous Altamont Speedway Free Concert in 1969, which the Rolling Stones had organised and for which the motorcycle gang reportedly provided security.



Meredith Hunter, a black 18-year-old member of the audience, was stabbed and kicked to death by a group of Hells Angels, in an attack captured on film cameras. As a result, Sir Mick allegedly refused to use their services again.
