LATEST: Former SOPRANOS star Michael Imperioli is "completely baffled" following a pipe bomb blast outside his New York theatre Studio Dante. Imperioli and his wife Victoria rushed to the scene after the bomb exploded outside the building at 1am on Tuesday morning (04Sep07). The actor tells the New York Daily News, "I don't know anything about this bomb in front of my theatre. I'm completely baffled. "I told (police) all I know, which is basically nothing. It's terrible, this whole day felt like an hallucination. It's surreal. We have the greatest police force in the world. I'm confident they will come up with something." No one was injured during the blast, but local residents were left shaken.
