What started as a hit-and-run accident where a driver displayed a firearm became even more complicated when law enforcement attempted to contact the suspect.

According to a media release from the Johnson County Sheriff’s Office, at roughly 1:30 p.m. the North Liberty Police Department was called to a hit-and-run accident where a driver reportedly displayed a firearm and left the scene.

Following this incident, the Johnson County Sheriff’s Office attempted “a short time later” to contact the suspect at a residence at 325 Division St. SW in Swisher, according to the release. The North Liberty Police obtained a search warrant for the residence and during the search of the premises officers discovered three suspected “homemade explosive devices.” The Johnson County Metro Bomb Team responded to the scene, removing the explosive devices from the home, and transported them to a gravel road where they were “rendered safe,” according to the release.

Police say the Bureau of Alcohol, Tobacco, and Firearms also responded to the scene and the agency is working with the Sheriff’s Office with the ongoing investigation. According to the release, evidence was collected at the scene that will be analyzed to identify the components of the devices.

No arrests have been made but charges are pending.
