An explosive device was detonated Friday morning by the back door of the US Social Security Administration office, shaking downtown Casa Grande, but no one was injured.

Federal agents, including those of the FBI, rushed to the scene. The FBI would not confirm whether anyone was in custody, but the Casa Grande Dispatch learned that a Coolidge resident, Abdullatif A. Aldosary, 47, was being questioned. The investigation involved agents’ going to his home at 4732 W. Lemon Ave., on the west side of Coolidge.

The device exploded at 8:24am. at the federal office, 501 N. Marshall St. The back door and wall were charred and debris was thrown throughout the back parking lot, damaging a car parked nearby.

The office was not yet open but more than 10 employees were inside, police said.

A witness was able to provide police with a license plate number on a small dark-colored compact car that fled the scene. The registration showed an address in the Martin Valley subdivision of Coolidge. Coolidge Police Department officers found the vehicle at the Lemon Avenue address. The homeowner, Aldosary, was turned over to the FBI shortly before 10am.

County recorder records show Aldosary bought the house on Aug. 12, 2008. According to court records, he was charged in September with assault and disorderly conduct. He also was charged in March 2008 with four counts of aggravated harassment at the request of the US Homeland Security Department.

FBI, Homeland Security, Federal Protective Service and US Bureau of Alcohol, Tobacco, Firearms and Explosives agents were at the scene collecting evidence throughout the day.

The office was closed after the blast Friday.
