Washington, Aug 22 : A British doctor who agreed to help Los Angeles police create a list of medics who helped facilitate Michael Jackson’s drug use has received death threats.

Dr. Susan Etok claims Michael Jackson tried to hire her as his own private physician but she turned down the offer because she disapproved of the drugs the King of pop was taking for aches and pains and a sleep disorder.

Now, she has become a police informant, naming some of the doctors the singer called on when he needed prescription pills and other medications.

"The police were most interested in the doctors I had seen around Michael," Contactmusic quoted Etok as telling U. S. news show Entertainment Tonight.

Etok insists that despite death threats she has received, she''ll continue to help police with their investigations.

"Somebody called me on my mobile and told me not to speak to the police and that if I did I''d wake up dead... The police are aware of it, the FBI are aware of it. It''s not going to stop me," she added. (ANI)
