GENEVA, Ill. (AP) — A former pastor of a now-defunct suburban Chicago church has been sentenced to 15 years in prison for sexually assaulting a teenager.

Ralphael J. Robinson was arrested and charged in April 2016 with aggravated criminal sexual assault and aggravated criminal sex abuse. Prosecutors alleged Robinson fondled and inappropriately touched the girl.

Robinson pleaded guilty in Kane County Circuit Court to aggravated criminal sexual assault of a minor while in a position of trust and authority. He was pastor of a North Aurora church at the time.

When arrested, the 41-year-old Robinson was on probation for failing to report to authorities a change of address as part of his lifetime sex offender registration requirements. The requirement stemmed from a Cook County sexual abuse conviction in 2004.
