A Bucks County woman on federal probation for a firearms violation was arrested at federal court in Philadelphia yesterday after an explosive device and the makings of a time bomb were found in her purse, authorities said.
Donna L. Bullington, 35, of Morrisville, entered the lobby of the courthouse, Sixth and Market Streets, about 1:30 p.m. to visit her probation officer, according to U.S. Marshal Thomas Rapone. The woman is on five years' probation for the federal firearms violation, Rapone said.
