Sam Lufti is being investigated by LAPD’s Major Crimes Division over claims he drugged Britney Spears.

According to “law enforcement sources”, the investigation is now underway following the allegations from the troubled pop star’s conservators.

They allege the former paparazzi photographer used the drugs to keep his ‘girlfriend’ Britney under his influence.

Although they refused to comment on the allegations, the TMZ website says Lufti’s spokesperson Michael Sands confirmed his knowledge of the case.
