Indiana University–Purdue University Indianapolis men's basketball coach Jason Gardner was arrested on suspicion of operating a vehicle while intoxicated in Hamilton County.

According to officials at Hamilton County Jail, Gardner was booked into the jail over the weekend and released early Tuesday on his own recognizance. He was taken into custody by the Fishers Police Department.

Gardner resigned from his post at IUPUI Tuesday, Assistant Athletic Director Ed Holdaway confirmed. Holdaway said it was a mutual decision between Gardner and the university, adding "we certainly wish him the best."

The OWI investigation began around 4:30 a.m. Sunday when police were called to the intersection of Cumberland Road and Bruddy Drive to check on the welfare of a man driving a 2016 Nissan.

Officers were there on a report that the vehicle had stopped in the intersection for unknown reasons.

Officers from the Fishers Police Department arrived at the scene and found Gardner asleep behind the wheel, police said. After multiple unsuccessful attempts to wake Gardner, officers entered the Nissan and took it out of gear.

Police said Gardner was asked to step out of the vehicle, and officers noticed that he was staggering and smelled of alcohol. Gardner submitted to multiple field sobriety test and failed each one.

Gardner, the 1999 IndyStar Mr. Basketball out of North Central High School, is entering his sixth season as IUPUI's head coach and has a 64-93 career record. Fox59 reports that assistant head coach Byron Rimm II has been named interim head coach for the 2019-2020 season.

Rimm II was hired Nov. 2018 as associate head coach and has 11 years of head coaching experience. He was head coach at Prairie View A&M from 2006-15. He directed Cal State San Bernardino to a No. 3 national ranking in NCAA Division II during the 2000 campaign and then took over as the head women's basketball coach at Texas College in Tyler, Texas.

He then had a four-year run as the head men's coach at Jarvis Christian College before joining Prairie View A&M as an assistant for the 2005-06 season. He was promoted to the head coaching spot the following season at age 32.

Gardner played college ball at the University of Arizona. According to IndyStar archives, after a professional playing career in Europe, Gardner served as an assistant coach at Cathedral High School for the 2010-11 season.

He then spent two seasons as an assistant at Loyola and then became an assistant coach at Memphis. He took over the IUPUI head coaching job in 2014 after former coach Todd Howard was fired.

His Mr. Basketball run saw him lead the North Central Panthers to the Class 4A championship. He went on to earn All-America honors at Arizona, where his No. 22 jersey was retired. He finished his career third on the school's all-time scoring chart.
