LONDON - A Beverly Hills plastic surgeon has become the third doctor to be investigated in Michael Jackson’s death.

Dr Larry Koplin’s clinic was raided as the probe into Jacko’s skin doctor Arnold Klein gathered pace.

LA assistant chief coroner Ed Winter marched into Koplin’s clinic to search for the singer’s medical files, the Sun reports.

Botox specialist Koplin has dismissed claims that the icon underwent a skin peel to lighten his skin.

He has reportedly said that the singer was advised a cream for the purpose.

Meanwhile, Winter has said that Koplin is “co-operating” in the probe.

The cop reportedly looked at papers kept by nurse David Fournier who worked at Koplin’s office as an anaesthetist.

Jackson’s personal physician Dr Conrad Murray - who is at the centre of a manslaughter probe - has had his premises searched already. (ANI)
