Topeka, KS - The FBI is investigating a threat against water systems in four Midwestern cities.
The FBI said Friday it hasn't confirmed any threats to the four cities.
A spokeswoman for the agency would not name those cities, saying only that they were confined to the Midwest.
Topeka city spokesman Suzie Gilbert says that the city is aware of the reported threats and because it targets Midwest cities, they have taken appropriate precautionary measures to monitor the water quality.
She says should any unsafe conditions be identified, the city will immediately notify the public.
