A 13-year-old boy has been arrested after he allegedly left a threatening voicemail for a Georgia chapter of the NAACP.

Local NBC affiliate 11 Alive reports that the 13-year-old allegedly called the Cobb County NAACP in late February and left hateful messages.

"My number is kill n*ggers 101," he said on a voicemail. "My name, Johnny Rebel. My profession murdering black people. F*ck you stupid f*cking n*ggers... F*cking kill yourself. Stupid n*gger-loving Jews."

Cobb County and Marietta City detectives worked with FBI agents to track down the suspect, whom they determined was a 13-year-old boy. After conducting an interview with him, they charged him with making terroristic threats. He is now in the custody of the juvenile detention system.

Phyllis Blake, the president of the Georgia NAACP, said she was appalled that anyone could leave such messages for her organization.

"It is just unbelievable that we have people like this in our world and we just have to remember when we hear that not to let us deter us from what we are doing but to continue to fight for everyone," she said.
