OMAHA, Neb. (AP) — Police say the landlord of a recently raided apartment found a package containing more than $20,000 days after its tenants were arrested.

The Omaha Police Department says the landlord entered the apartment Saturday to check for damages after Nebraska State Troopers searched the residence and arrested the tenants three days earlier. Inside, the landlord discovered a 6-by-8 package wrapped with black duct tape next to two pillows and a blanket.

Police say they determined the package was safe and opened it to find $20,780 inside. It remains in police custody.

A state patrol member who conducted the March 18 raid says it seemed the apartment had been entered since the raid. The purpose of the raid was not disclosed.
