Okoh, 40, had taken over the Bison program last year after longtime coach Keith Tucker was fired.
Okoh was charged with one felony count of using a communications system to solicit a person under 15 years old with lascivious intent. He is accused of traveling from his home in Arlington for the purpose of engaging in sexual activity with a person he thought was a 13-year-old girl. The person was actually an undercover deputy.
Okoh was suspended from all university activities and duties pending completion of the investigation.
