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 (http://bit.ly/1gN9Vnk ) 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.
