Georgia worker injured by mail explosion

NORCROSS, Georgia (CNN) -- An employee of a subsidiary of Home Depot was slightly injured when a suspected letter or package bomb went off in her face, police said Wednesday.

The 33-year-old woman, whose name was not released, was at work at Apex Supply Co. in east suburban Atlanta when the explosion occurred.

Later in the morning, the 4,000 employees of Home Depot's corporate offices in Atlanta were evacuated after a suspicious package was located in the building's mailroom, a company spokesman said. There was no explosion and the package was being investigated.

The Apex Supply worker was treated at Gwinnett Medical Center for a facial injury and minor burns, said Paula Martin, a spokesman for Gwinnett Health Systems. The woman was in good condition and was expected to be released shortly.

Martin said a second person who was standing nearby when the letter exploded was checked for a possible eye injury, but none was found.

The building was evacuated after the explosion. County police and federal Bureau of Alcohol, Tobacco and Firearms agents were conducting a precautionary search for other devices.

At Home Depot corporate headquarters in Atlanta, spokesman Jerry Shields said the evacuation of that building was called as a precaution after the suspicious package was located in the mailroom. "Authorities are investigating it right now," he said.

Shields did not know how or when the package was discovered. The decision to evacuate was made by company authorities, he said, who were in touch with the Cobb County fire and police departments.

The evacuations come four days after a weekend shooting at an Atlanta-area Home Depot that left three people, including the shooter, dead. The gunman was apparently following his former girlfriend when she stopped at the store to seek refuge; the boyfriend followed her in and opened fire before killing himself.

Apex Supply Co. was purchased by Home Depot in early 2000, and deals in supplies and tools for heating and air conditioning, plumbing, kitchen cabinets and more.
