DES MOINES, Iowa (AP) — The Iowa Department of Corrections tells The Associated Press that about 80 inmates at a maximum security prison could face disciplinary action in connection to a large fight this month. That’s a far greater number of people than the state corrections department has publicly said were directly involved in the July 1 melee at the Iowa State Penitentiary in Fort Madison. The estimate could add weight to union claims that the state agency previously has downplayed the fight.

DES MOINES, Iowa (AP) — Iowa Republican Sen. Rick Bertrand has called on Senate Majority Leader Bill Dix to resign following the conclusion of a sexual harassment lawsuit filed by a former legislative aide. Bertrand said Wednesday that Dix should resign after a jury awarded $2.2 million to Kirsten Anderson, a former Iowa Senate Republican caucus aide. The jury determined she was fired in 2013 after she reported rampant sexual harassment in the caucus office. A spokesman for Dix says the senator has no comment.

DES MOINES, Iowa (AP) — Law enforcement officials in central Iowa are warning of a familiar phone scam. The Polk County Sheriff’s Office tells KCCI that people are receiving telephone calls claiming to be from the sheriff’s office. The caller tells recipients there is a signed a warrant for their arrest for not showing up for jury duty. Victims are then told to retrieve a large amount of cash and follow further instructions to avoid being arrested.
