Michael Jackson's Dr Conrad Murray has threatened to disclose a "nuclear" secret if he is forced to testify in a 100-million-pound damages case.
Murray, who is serving four years for the King of Pop's involuntary killing, has suggested that he has been harbouring bombshell information regarding Jackson's true relationship with his family, who are suing promoters AEG Live, the Mirror reported.
The doctor sent the message via a pal, warning not to incite him to testify.
It seems that Murray is refusing to get involved in the court case as he does not want to be incriminated.
Jackson's mum Katherine, 83, and his three children are suing AEG, claiming the 'This Is it' tour promoter neglected the singer's health prior to his death in 2009.
