Chris Soules, who rose to fame as a star on the reality television series “The Bachelor,” was arrested by the authorities in Iowa after they said he fled the scene of a crash that killed one person.

Around 8:20 p.m. Monday, the Buchanan County Sheriff’s Office received a report of an accident near the northeastern city of Aurora, the sheriff’s office said in a statement. Investigators said Mr. Soules, 35, was driving a 2008 Chevrolet Silverado southbound when he rear-ended a John Deere tractor that Kenneth Eugene Mosher, 66, was driving.

The collision caused the tractor to go into a ditch, and the authorities said Mr. Mosher was taken to a hospital, where he was pronounced dead.

Mr. Soules’s truck went into a different ditch, but the sheriff’s office said he was not injured in the accident and left the scene before deputies arrived.
