The King of Pop's family took the decision after they found out that the 'Thriller' star gave a sperm sample to a Los Angeles donor bank last year, when he was considering having a fourth child.
And as the legal battle over the singer's multi-billion dollar estate is going on, the Jacksons are not ready to trust anyone. Friends close to the family fear that rogue elements could use the sperm sample to give birth to a new claimant to Jacko's riches.
"It might sound crazy but when it comes to Michael anything is possible," the Mirror quoted a source as saying.
It was recently revealed that the singer approached British doctor Susan Etok last October about having his fourth child.
"With everything that's at stake the last thing the Jackson family need is someone using his sperm to give birth to a child and produce another potential heir to Michael's estate," said a source.
"The family know Michael authorised a number of people to access this sperm sample. The problem is they don't know who has access and given that a number of doctors have been implicated in his death then something sinister could easily happen," added the source.
Another reason for Jackson storing samples could be that he knew his drug problems might damage his DNA. The sperm was cryogenically frozen to allow it to be preserved indefinitely.
Moving the sample to London would cost 900 pounds for transport. The annual storage fee would amount to another 125 pounds.
