A Davenport man was arrested Tuesday after police say he set fire to a Davenport Police Department traffic speed trailer.
Craig M. Petersen, 27, was in the Scott County Jail on a second-degree arson charge, which is a felony.
The fire happened sometime after 11 p.m. Monday in the 2600 block of West 68th Street, a news release from city of Davenport spokeswoman Jennifer Nahra said.
The speed trailer is used to slow traffic and alert motorists to the speed of their vehicles, but it does not issue tickets, the release said.
