ROMULUS, Mich. (WJBK) - Officials are investigating the tampering with soap dispensers at Detroit Metropolitan Airport in Romulus.
A foreign substance was found in some of the bathroom soap last week, sparking the investigation.
"Our Public Safety Department is investigating an unusual substance found in a few of our soap dispensers during the last week," said airport spokesperson Erica Donerson in a statement. "The Airport Authority takes incidents involving health and safety very seriously."
The incident has led to new dispensers in the restrooms at Metro, she added.
No official details have been released yet about what the unusual substance was, but FOX 2 has learned it is believed to be a man's bodily fluid.
"We are in the process of installing new, tamper-proof soap dispensers and are more frequently monitoring our restrooms," she said.
FOX 2's Taryn Asher will have more on this story tonight at 10 and 11 p.m.
