(KNZA)--A Topeka man convicted in Brown County of the electronic solicitation of a person he believed to be a child between 14 and 16 has been sentenced to more than 4 1/2 years in prison.

Following the presentation of evidence from several witnesses, including an expert witness in psychology, Brown County Attorney Kevin Hill said 51-year-old Dennis Prochazka’s motion for probation was denied Monday and the state’s request for imprisonment was granted.

Hill said District Judge Jim Patton sentenced Prochazka to 55 months in prison.

Prochazka pleaded no contest in March to the felony charge.

He was arrested in March of 2018 following an investigation by undercover officers with the Hiawatha Police Department.

Following his sentencing, Prochazka's bond was revoked and he was remanded to the Brown County Jail for delivery to the Kansas Secretary of Corrections to begin serving his prison sentence.

After serving his sentence, he will be required  to register as a sex offender for a period of 25 years.
