FBI: Ex-doctor from Cuyahoga Falls admitted making pipe bombs

CLEVELAND -- Federal agents in Ohio say a troubled former doctor admitted making pipe bombs that were part of an arsenal seized at his apartment.

An affidavit filed in federal court in Akron says Mark Campano, 56, of Cuyahoga Falls told an FBI agent that he "did indeed" build the pipe bombs found this week at his apartment.

Neither Campano nor the FBI describes a motive in the affidavit, which was filed late Wednesday.

A message seeking comment was left Friday for Campano's court-appointed attorney Donald Hicks.

Authorities arrested Campano after an explosion rocked his apartment complex Monday night.

Police said he was attempting to load shotgun shells when one blew up.

Campano's Ohio medical license was revoked in 2006 because of a 19-year history with drug abuse.
