A group of Iowa businessmen filed a lawsuit on Wednesday against United Airlines over the death of a giant rabbit after a flight from London to Chicago.

The businessmen filed the lawsuit more than three months after airline workers found the continental rabbit named Simon dead on April 20. The animal had been placed in a United kennel in Chicago's O'Hare airport while awaiting a connecting flight to Kansas City, where his new owners planned to pick him up.

The lawsuit seeks unspecified damages to cover the costs of the rabbit as well as punitive damages.
