‘Unusual’ Substance Discovered in Soap Dispensers at Detroit Metro Airport [VIDEO]

Maintenance workers at Detroit Metro Airport are working to replace soap dispensers in restrooms at the facility after an unusual substance was discovered in many of them.

Authorities tell WDIV the substance is likely some sort of bodily fluid, but say it is not spit.

Airport authorities suspect the culprit is someone who has access to the restrooms and has some sort of grudge.
