KENNEBEC-A Sioux Falls man will spend two years in prison for threatening a law enforcement officer with a knife on his way to jail.

Antonio Hampton, 53, was arrested Jan. 12 when the South Dakota Highway Patrol was alerted of a car speeding on Interstate 90. A highway patrol officer located a vehicle matching the description parked in Vivian and reportedly observed it crossing the center line on U.S. Highway 83 while traveling 96 mph.

Hampton pulled over and reportedly told the officer he was on his way to Iowa, although he had been driving north. He was arrested for a first-offense DUI after giving a PBT of 0.177.

While being transported to jail, Hampton threatened the officer with a pocket knife and reportedly said he wasn't going back to prison. Law enforcement was able to take the knife away from him at the jail only after he ignored instructions and was tased.

Hampton was originally charged with aggravated assault against a law enforcement officer, a first-offense DUI, obstructing police, intentional damage to property of $400 or less and speeding on a divided highway.

He pleaded guilty on Feb. 6 to the property damage charge and simple assault against a law enforcement officer, and the rest of the charges were dropped.

Hampton was sentenced to two years in the state penitentiary with credit for 54 days served for the assault and ordered to pay $161 in fines and court costs. He will serve no additional time for the property damage conviction but must pay $533 in fines, court costs and restitution.
