Jackson death 'being treated as homicide'

The Los Angeles Police Department has begun treating Michael Jackson's death as a possible homicide, according to TMZ.

The website has alleged that "multiple" sources within the LAPD are reporting that the investigation is being focused on Jackson's former doctor.

Law officials are quoted as saying there is "plenty of powerful evidence" to link Dr Conrad Murray to an anaesthetic called Diprivan, which the star is alleged to have taken.

It is reported that the evidence includes items found in Jackson's rented home, including the painkillers, an IV stand and an oxygen tank.

The celebrity website also claimed that the LAPD had already held "multiple conversations" with the LA County District Attorney's office about the case. An attorney for Murray has reportedly refused to comment on whether his client administered the drug.

Earlier today, it was reported that the LA Coroner's Office had subpoenaed the singer's former dermatologist Arnold Klein in order to examine "additional medical records".
