The trailers were found in the Bronx borough of New York Saturday, but the bananas were mysteriously absent, The New York Post reported.

"Someone's got a whole lot of potassium," Delaware State Police Cpl. Jeffrey Whitmarsh said.

Whitmarsh said the banana trailers went missing Thursday and a New York police officer discovered them unattended along the road.

Officials said an investigation of registration plates indicated someone stole the fruit-filled trailers.
