The arrest comes days after FBI agents searched a home in Horry County, South Carolina, associated with John-Paul Miller. However, the arrest is not related to the FBI search.
Instead, arrest warrants show that the assault was associated with a dispute between John-Paul and a group of female protesters near the church where he's a pastor.
John-Paul's attorney Russell Long told WMBF that the protesters were antagonizing John-Paul and "trying their best to drive him crazy."
According to the arrest warrant, John-Paul "tapped the brim of the (victim's) baseball cap" and then walked away. A witness told police "she observed the defendant hit the (victim's) hat twice."
John-Paul was arrested and charged with third-degree assault and battery. He was released from jail Thursday morning on a $776 bond.

John-Paul was married to Mica Miller, but the couple were going through a divorce prior to her death.
Some of Mica's friends and family have accused John-Paul of abuse and playing a role in her death. John-Paul has vehemently denied all those accusations.
John-Paul has not been charged with any crimes related to Mica's death.
