It sounds like Sioux Falls isn't the only town with a ninja problem.

On Monday (June 11) a Tiffin, Iowa man was arrested outside a gas station after threatening customers with a sword, guitar and throwing knives.

21-year old Deandre Irby was arrested outside the Kum & Go in Tiffin after officers responded to a call of a man outside bothering patrons with a guitar.

When police arrived, they say a handle sticking out of the back of Irby's shirt. When asked what it was, Irby admitted it was a sword.

Police say they took the "samurai-type" sword from Irby, who also had two throwing knives and a flask with a white powder substance that he told police was "probably coke," according to the complaint.
