The Army Corps of Engineers will be returning to an Orlando middle school to search for World War II explosives that might be buried there.

The federal agency will inspect part of the Odyssey Middle School campus where 15 portable classrooms are being removed because of declining enrollment. Corps officials hadn't been able to search that area with metal detectors and other bomb finding technology before.

More than 400 pounds of World War II-era bombs and munitions were unearthed from the grounds around the middle school over the winter holidays last year. Part of the school grounds had been used by the Army in the 1940s to train bombardiers for combat.

Munitions have also been found in backyards and construction sites.

The new search is scheduled to begin in December.
