MANCHESTER — A former pastor of a Manchester church is facing sexual assault charges involving minors.

Stephen Jesmer, 37 of Manchester, turned himself in on Monday. He was being investigated by Manchester juvenile investigators for several months following an alert of inappropriate behavior involving the former pastor and a minor. The investigation led to an arrest warrant.

Jesmer is charged with three counts of aggravated felonious sexual assault, three counts of felonious sexual assault, and one count of witness tampering.

He was previously employed as a pastor with The Dialogue Church, 516 Pine Street at the time of the alleged assaults.

Jesmer was set to appear in court on Tuesday.
