London, Aug 26 - Michael Jackson's doctor Conrad Murray allegedly spent 47 minutes calling up another medic, a lawyer and an unknown associate after the pop music icon died.

According to thesun.co.uk, Murray panicked and called up his doctor friend Arnold Klien for advice on what he must do as Jackson lay dying. He also supposedly called a lawyer before he told a security guard to dial 911 and call for paramedics.

Both Murray and Klein are being investigated by police over their role in Jacko's death, which is being treated as homicide. The King of Pop died June 25.

Murray had earlier claimed that he tried to revive Jackson, but court papers that were leaked show that he spent 47 minutes where he made three separate calls.

Steven Hoefflin, who treated Jackson for 25 years, said: 'Murray definitely called Klein because Klein taught him how to administer propofol. There were two in-state calls then one out-of-state. He was calling an attorney -- he had to because Michael was dead. He tried to cover it up by telling everyone Michael had a weak pulse, but Michael was dead.'
