Authorities have arrested a Swisher man after they say they discovered homemade explosives inside his home Thursday.

"Lance Edmund Degen, 24, of Swisher was taken into custody today in connection with the incidents that occurred in North Liberty and Swisher on Thursday, June 14th, 2018," authorities said in a news release Sunday. "He has been charged with Carrying Weapons, Assault While Displaying A Dangerous Weapon, and Possession Of An Explosive or Incendiary Device."

Authorities said the incident began about 1:30 p.m. Thursday in North Liberty. Police there responded to a hit and run crash involving a driver who displayed a firearm and left the scene.

Sheriff's deputies tried to contact the suspect at his home, 325 Division Street SW in Swisher, a short time later.

North Liberty Police obtained a search warrant for the house. Inside, officers found what they believed to be three explosive devices. A bomb disposal unit was called in to secure the devices. The team took them to a gravel road and detonated them.

Authorities said Degen's charges are aggravated misdemeanors, punishable by up to six years in prison. His bond was set at $15,000 cash or surety.

Degen will make an initial court appearance Monday, June 18th.
