LE MARS, Iowa | Two Sioux City residents were arrested Sunday morning after two bicyclists reported they were shot at while riding in a rural area of Plymouth County, authorities said.

No one was injured.

The Plymouth County Sheriff's Office said in a release that the cyclists, Tony Pierce and John Pecaut, of rural Sioux City, were traveling along Highway 12 when a red Ford Explorer approached them and slowed down. The driver pointed a firearm out the diver's side of the vehicle and discharged several rounds.

Pierce and Pecaut took cover in a ditch and called 911. 

Terry Lee Oliver Jr., 22, and Cesar Teodoro Gonzalez, 20, were arrested after officers tracked down the vehicle four miles north of where the shots allegedly were fired. The suspects attempted to flee the vehicle, running into a wooded area along the Big Sioux River, the release said.

The suspects were apprehended without incident and were being held in Plymouth County Jail. The alleged weapon was found in a wooded area by a Woodbury County Canine.

Oliver was charged with attempted murder, a class B felony, and Gonzalez was being held on a material witness warrant.
