(MCT) — William Cellini, the Springfield insider who awaits sentencing for joining a conspiracy to extort campaign cash for political access, was released from a hospital Wednesday after suffering a heart attack two days earlier, a spokesman said.

Cellini, 77, had gone to Memorial Medical Center in Springfield for a stress test and an angioplasty procedure after experiencing fatigue and difficulty breathing, spokesman Dick Ciccone said.

The angioplasty showed two blockages of an artery leading from the heart. A stent was inserted which led to complications that led to the heart attack, Ciccone said.

Cellini was convicted by a jury in November of conspiracy to commit extortion and aiding and abetting in the solicitation of a bribe. He was acquitted of a third count.
