Authorities are investigating a motorcycle accident that injured a Shell Rock man.

Chad Martinson, 49, was sent to the Waverly hospital for treatment after losing control of his motorcycle on the southern edge of the city around 5:15 PM Monday. The extent of his injuries wasn't released.

According to an Iowa State Patrol crash report, Martinson was exiting U.S. Highway 218 and merging onto Business U.S. 218 when he drove off the pavement and lost control. The motorcycle slid across both northbound lanes and came to rest in a ditch.

Charges against Martinson are pending, the Iowa State Patrol said.

Bremer County sheriff's deputies, Waverly police, Waverly firefighters and Waverly ambulance personnel assisted state troopers at the scene.
