There's a disgusting and disturbing story out of an airport with multiple flights a day to and from South Bend.

Police in Detroit say they found a bodily fluid in soap dispensers in restrooms at Detroit Metro Airport.

Police aren't saying what the substance was because they haven't tested it, but they say they're fairly certain they know what it is.

Investigators say the culprit is likely someone with ongoing access to the restrooms who has a grudge.

The airport is pulling its current soap dispensers and is replacing them with tamper-proof devices to keep it from happening again.

According to airport officials, only some of the bathrooms at the North Terminal were affected, and none in the McNamara Terminal were affected.
