ESTHERVILLE, Iowa (AP) — A squirrel roaming a community college in northern Iowa has become the No. 1 suspect in a vandalized bicycle incident.

Officials at Iowa Lakes Community College in Estherville say the rodent chewed through two tires, a bicycle seat, a headlight and a taillight in the span of two days beginning Wednesday.

The Sioux City Journal reports the bicycle owner, an associate math professor, reported the incidents to Estherville police. Another professor later came forward with a photo that shows the squirrel attacking the bike.

A school spokeswoman says the photo helps solve the mystery of how the bicycle was vandalized without witnesses seeing a suspect.

The professor has since parked his bicycle indoors.
