DES MOINES, Iowa (AP) — A newspaper has reported that a Drake University professor accused of sexually exploiting female students has been allowed to resign effective June 1. The Des Moines Register reports that a November internal investigation found that Mahmoud Hamad “physically, sexually and verbally intimidated” female students and “did exploit the power differential that existed between him and his female students.”

The report found that Hamad violated university policies through “unwelcome advances and unwelcome verbal and physical conduct and intimidation aimed at female students because of their sex.” The case hasn’t been referred to police. In the report Hamad denied the student accusations. He’s declined to otherwise comment. Drake administrator Sue Mattison won’t say whether Hamad was asked to resign. She says he’s on a leave of absence.

WELLMAN, Iowa (AP) — A former Iowa teacher purged from the state’s sex offender list has been allowed to volunteer at an eastern Iowa school district. The Des Moines Register reports that Trent Yoder has been helping out in the Mid-Prairie schools district, which is based in Wellman. The district granted him special permission to volunteer, after receiving letters of support. Superintendent Mark Schneider says he has informed school principals that Yoder must be with another adult at all times.

Yoder had pleaded guilty to exploiting a minor at an Anita school by videotaping a high school athlete changing her clothes in 1998. Court records say he served a few weeks behind bars and then four years of probation. He was removed from the sex offender registry after 10 years. He told the Register that he hates that he “caused so much pain to that community.”

The Iowa State Patrol, Thursday, released additional details about an accident Wednesday morning involving a Trooper. Authorities report Trooper Dillon Malone, of Council Bluffs, was driving his patrol vehicle, a 2014 Dodge Charger, in Emergency status, while enroute to assist with a vehicle eluding law enforcement. As the Trooper was traveling south on Highway 275 at around 4:20-a.m., and entering the town of Hamburg, his vehicle entered a curve and went out of control. The cruiser went off the road to the left and into a residential yard where it hit a tree before going airborne off an embankment. The vehicle struck a parked 2017 Freightliner semi trailer in the residents’ driveway, and afterward spun around before coming to rest.

Trooper Malone, who was wearing his seat belt, was transported by LifeNet helicopter to the University of Nebraska Medical Center (UNMC), where he was being treated for serious, but non-life threatening injuries.

DES MOINES, Iowa (AP) — Des Moines police have arrested a man who they say surrendered after firing a pistol at an officer, who fired back. Police identified the man as 21-year-old Benjamin Perry, who’s been charged with assault with a dangerous weapon on a police officer and other crimes.  Police say no one was injured in the gunfire exchange, which occurred around 2 a.m. Thursday toward the end of a pursuit on northbound Interstate 35.

Officers deployed stop sticks that disabled the vehicle. Police say the man later identified as Perry fired as his vehicle slowed, and the officer returned the fire. Officers say Perry surrendered after a brief standoff and was taken to a hospital for observation.
