PICKENS — An Easley man was arrested this week after police say he sexually assaulted a child last month.

Wolfgang Dylan Stein, 28, was served with a warrant for first-degree criminal sexual conduct with a minor after being picked up from an Anderson County facility where he had been held for several days on unrelated federal charges, according to Pickens County Sheriff’s Office chief deputy Creed Hashe.

Hashe said the sheriff’s office began an investigation on March 3 after receiving information that a child under the age of 11 had been sexually assaulted that morning at a home in Pickens County.

Detectives were able to find and interview the child’s mother, who police said witnessed the alleged incident.

Although he did not give details about their relationship, Hashe said Stein knew the woman and her child.

Stein was given no bond by a Pickens County magistrate on Monday and was transported back to Anderson County, where he was released back to authorities there.
