Authorities in Florida said they arrested a man who allegedly faked an armed robbery to gain sympathy from his estranged girlfriend.

The Martin County Sheriff's Office said Derick Culberson, 22, of Palm City, told deputies Friday night that two men armed with a silver pistol stole his vehicle's GPS device and bound his hands and ankles with plastic zip ties, TCPalm.com reported Tuesday.

Investigators said inconsistencies in Culberson's story made them suspicious and they discovered zip ties in his truck that were similar to the ones on his wrists and ankles when deputies arrived on the scene.

The sheriff's office report of the incident states Culberson eventually admitted to inventing the robbery "in an attempt to make his girlfriend feel bad for leaving him."

"Culberson admitted to tying his own hands and feet, and further inventing the suspects' vehicle and weapon descriptions that he gave to sheriff's office dispatch and deputies," the report states.

Culberson was arrested and charged with misdemeanor false report of the commission of a crime. He was released Saturday from the Martin County jail after posting $250 bail.
