Authorities say actor Corey Haim had a fraudulent prescription when he died that was linked to a major drug ring. The California Attorney General's Office said Friday it was investigating the drug ring and how Haim obtained the prescription. The agency offered few details in a news release and a spokesperson did not immediately return a call seeking more information. Coroner's officials in Los Angeles County, where Haim died Wednesday, say four prescription drug bottles in the actor's name were found in an apartment where he collapsed. The coroner's office has declined to state what medications were found, but said no illegal drugs were discovered. Haim battled addiction for years. The Canadian-born actor gained fame after starring in 1980s flicks “The Lost Boys” and “Lucas.”
