WIESBADEN, Germany – Some residential buildings on Heidelberg’s Patrick Henry Village were briefly evacuated last week as bomb disposal experts cleared World War II-era unexploded ordnance that a soldier was keeping in his quarters, garrison officials said Tuesday.

U.S. Army Garrison Baden-Württemberg spokeswoman Regina Hingtgen said the soldier was a collector of WWII weapons and munitions.

“It wasn’t a bomb threat, just a collector,” Hingtgen said.

Hingtgen said the soldier had shown someone his collection and that as far as she knows, that person contacted the authorities.

Officials have not released the soldier’s identity or what, if any, disciplinary action the soldier could potentially face.
