Lindsay Lohan’s father claims he can identify the person selling the star drugs.

Michael Lohan – who has alleged his actress daughter is addicted to prescription drugs – believes the ‘Mean Girls’ star is being targeted by a man who is aware of her reliance on legal substances.

“This guy follows Lindsay all over the place. All over. Lindsay pays for him to go everywhere. He has no job. He does nothing. All he does is supply everyone in Los Angeles,” Michael — who has a history of drug abuse himself — revealed in an interview with RadarOnline Wednesday.

The born-again Christian has vowed to help Lindsay beat her addiction, telling Radar: “I’m going to get her off the prescription drugs that she’s on. I hate it when people talk about illegal drug abuse because it’s not just drinking and illegal drugs that kill you,” he added.

“Prescription drugs can destroy and kill a person and are sometimes harder to stop. Look at Heath Ledger and Michael Jackson.”

Although he refused to say what medications his 22-year-old daughter is taking, he admitted her addiction has taken over her life.
