Vince McMahon, the wrestling impresario, and his World Wrestling Federation have been indicted in Brooklyn on Federal charges that they conspired for years with a convicted steroid dealer to distribute anabolic steroids to W.W.F. wrestlers.

The primary case against McMahon was apparently developed with the cooperation of Dr. George Zahorian 3d, a Pennsylvania physician who was listed in the indictment as an unindicted co-conspirator. Zahorian was convicted of steroid distribution in 1991 after a Federal trial in Pennsylvania, in which he testified that he had supplied steroids to Hulk Hogan and other W.W.F wrestlers.

In a statement issued through his lawyers, McMahon said the prosecutors "are now trying to make me responsible for what the doctor did. I did no such thing."

On a separate charge of possession with intent to distribute steroids to a W.W.F. performer in October 1989, McMahon, who had previously acknowledged having used steroids before simple possession became a Federal crime in 1991, said the prosecutors, "claim that I shared some of those steroids with a friend and that somehow made me a dealer."
