A New Hampshire pastor has been arrested on a charge of possession of child sexual assault images. Police said Tuesday the arrest of 46-year-old Stephen Bates, the pastor of the Bible Baptist Church in Nashua, came after the Hillsborough County Sheriff’s Office executed a search warrant at the church parsonage and found two flash drives containing “numerous” child pornography images. His bail was set at $3,000. It wasn’t immediately known if Bates had a lawyer. Nashua police said in a news release that an investigation involving the church began in 2016.
