A trooper with the Iowa State Patrol has resigned after being arrested following a drunken, late-night disturbance in which the former college football player repeatedly pounded on a female neighbor's door, according to public documents obtained by The Associated Press.

Following his arrest, Cedar Rapids-based trooper Patrick Steinbach received special treatment at the Iowa County Jail, where the booking officer did not take his mug shot, require him to wear a jumpsuit or have him fill out a standard form answering questions about his intoxication and medical history. The booking took three hours — "an extraordinary amount of time" compared to the typical hour, Sheriff Rob Rotter said today.

Rotter said the booking officer is no longer employed after an internal review found numerous policy violations.

"He was just being incredibly nice and friendly to him and maybe being more of a friend than a booking officer," Rotter said. "The performance of that employee was incompatible with our policies and procedures. It was brought to the attention of that employee and a change was made."
