The inmate accused of attacking the notorious Charleston church killer, Dylann Roof has been freed after an anonymous person posted his $100,000 bond, presumably as a "thank you" for his efforts. 

26-year old Dwayne Stafford had served 18-months at Charleston County Jail for first-degree assault and strong armed robbery charges, but once he got his hands on that scumbag Roof, someone quickly posted his six-figure bond. 

Authorities said that although Roof is in protective custody, he was assaulted last Thursday while heading to the shower thanks to a "mistake" which led to Stafford's cell being unlocked during the transfer. 

Dwayne Stafford ran down the stairs from his cell after Roof went into the shower around 7:45 a.m. Thursday and hit him, bruising Roof's face and back, according to a police report.

Officials are investigating how Stafford managed to get through a cell door to reach Roof. The two detention officers assigned to the unit are being interviewed. Officials also are looking into the possibility of an electronic malfunction, Cannon said.

The 22-year-old Roof was examined by jail medical personnel and then returned to his cell, Charleston County Sheriff's Maj. Eric Watson told The Associated Press.

While authorities earlier said Stafford would be charged with assault, Charleston County Sheriff Al Cannon told reporters that Roof and his attorneys don't want to press charges.

Roof faces the death penalty for the June 2015 murder of nine black church goers during a Bible study at Emanuel AME Church in Charleston, South Carolina. His trial is set for November.
