U.S. Immigration and Customs Enforcement officials say about $387,000 was seized from three people on a bus headed for Mexico.
Officials say police in Cuba, a town on Interstate 20 in west Alabama, stopped a bus Sunday and called federal authorities when a drug-sniffing dog alerted to substances stored in the luggage compartment.
Authorities say they searched three bags and found thousands of dollars stuffed into a blanket and shoes.
Department of Homeland Security spokesman Bryan Cox says no drugs were recovered, but added that the large amount of money may have come into contact with drugs at some point, which may have caused the dog to alert to it.
Authorities say owners of the bag didn't claim ownership of the money, and charges have not yet been filed. Cox says the incident is under investigation.
