WATERLOO, Iowa (AP) — An angry white officer repeatedly yanked on the dreadlocks of a handcuffed black man who was arrested after a dangerous high-speed chase in Iowa, then twice hit him on the back of the head. Video obtained by The Associated Press shows the officer briefly assaulting 24-year-old Montavis Keller and calling him names after the April 19 chase. A prosecutor has concluded that no charges are warranted against officer Adam Wittmayer, who was disciplined by his department.

CEDAR RAPIDS, Iowa (AP) — A Cedar Rapids man has pleaded guilty to one count of enticement of minors in connection with improper contact with three girls. The U.S. Attorney’s Office says 20-year-old Tyler Konigsmark, a former school bus attendant, pleaded guilty Thursday to the enticement charge and acknowledged that he used Snapchat and his mobile phone to request sexually explicit images of the girls, ages 12, 13 and 14. Konigsmark also admitted he twice had sex with the 12-year-old girl. He will be sentenced later.

ST. LOUIS (AP) — A Missouri judge has fined the state Highway Patrol $5,000 after finding that it violated open records law in responding to requests from the family of an Iowa man who drowned while in custody. According to the St. Louis Post-Dispatch, the judge ruled Wednesday that the state’s delays in turning over documents to Brandon Ellingson’s family amounted to a “purposeful violation.” Ellingson drowned in 2014 on the Lake of the Ozarks.

BLUE GRASS, Iowa (AP) — A construction work was killed when the driver of a speeding vehicle apparently lost control in a work zone near the southeast Iowa city of Blue Grass. The Scott County Sheriff’s Office says a deputy saw the speeding vehicle but before he could catch up to it the vehicle entered a work zone. The driver tried to exit the highway but careened into the construction area and hit a worker. The worker was pronounced dead upon arrival at a hospital. The driver and a child in the vehicle were injured.
