Authorities in southwest Iowa are now releasing details of a weekend incident where a man with a knife was tazered by law officers so he could be subdued and arrested. Pottawattamie County Sheriff Jeff Danker says it happened Friday night at a gas station along Interstate 80 at the Minden exit.

Danker says the suspect was brandishing a knife and acting irrationally. Danker says when deputies arrived, a D-C-I agent was already on the scene, pointing his weapon at the suspect. A sheriff’s deputy approached the man, who was in the store, yelling. The deputy ordered him to drop his knife and when he failed to comply, the deputy deployed the tazer and stunned the man. He was handcuffed and brought to the jail in Council Bluffs.

Sheriff Danker identifies the suspect as 39-year-old Marvin Hunt of Council Bluffs. Danker says Hunt had apparently entered the store earlier and talked with one of the employees. He allegedly demanded that everyone leave the business and made references to his having used drugs and other problems, that caused him to act out.

No injuries were reported. Danker says Hunt was charged with four counts of aggravated assault and going armed with intent. There’s also an outstanding warrant for his arrest.
