Rock legend Mick Jagger narrowly dodged an assassination attempt more than three decades ago, disclosed Mark Young, a former FBI officer, as quoted by BBC Monday.

The plot was hatched in 1969 by the Hells Angels, said Young in an interview for the BBC's "The FBI at 100" documentary.

Young said the infamous Hells Angels gang allegedly plotted to kill the Rolling Stones frontman following the Altamont Speedway Free Concert in 1969, where a teenager was killed.

The motorcycle outlaws were said to have provided security for the British band at the gig, but after 18-year-old Meredith Hunter was stabbed and beaten to death by members of the group -- in an attack captured by film cameras -- Jagger reportedly vowed never to use the gang's services again.

"The Hells Angels were so angered by Jagger's treatment of them that they decided to kill him," Tom Mangold, the presenter of the program, was quoted as telling Britain's Sunday Telegraph newspaper.

"They planned the attack from the sea so they could enter his property from the garden and avoid security at the front. The boat was hit by a storm and all of the men were thrown overboard. All survived and there was not said to have been any further attempt on Jagger's life."

It was not clear whether Jagger was ever informed of the alleged plot against him.

The Hells Angels have always denied any connection with the Altamont Speedway killing.
