Michael Jackson's former personal physician, Dr. Conrad Murray, will be arraigned in Los Angeles on Friday on a charge tied to the King of Pop's death, a source tells the Associated Press.

The AP says its source is a person familiar with the planning and did not specify what Murray would reportedly be charged with. Prosecutors have so far declined to say whether they'll charge Murray, but two law enforcement sources have told the AP that prosecutors intend to charge the doctor with involuntary manslaughter.

A spokeswoman for the L.A. Country district attorney said she could "neither confirm nor deny" that Murray would appear at the courthouse, near Los Angeles International Airport, on Friday afternoon.

Murray has denied any wrongdoing related to Jackson's death. ET confirmed that he is currently in L.A.
