An Indiana man has pleaded guilty to supplying explosives to a man implicated in the bombing of a video poker company and taking part in a suburban Chicago robbery ring.

Kyle Knight of Merrillville, Ind., entered his plea Wednesday before U.S. District Judge Robert Gettleman.

He admitted supplying the explosives to 84-year-old Samuel Volpendesto, who was arrested recently as federal agents staged high-profile raids on Chicago-area meeting places of the Outlaws motorcycle club.

Volpendesto is one of two men charged in the video poker bombing.

In his signed plea agreement, Knight alleges that Volpendesto admitted to him that he had ties to organized crime.
