CNN identified Nzinga as the chief of staff of the New Black Panther Party. According to a DeKalb arrest warrant, Nzinga was in possession of an FN Herstal 5.7 x 28 handgun, which investigators said he pawned at a shop on Rockbridge Road. That alleged transaction would be illegal due to Nzinga’s convictions last month for felony deposit account fraud in Gwinnett County, the DeKalb Sheriff's Office said. Nzinga was arrested by members of the fugitive squad at a probation office in Lawrenceville and transported to DeKalb County Jail. The New Black Panther Party is offering a $10,000 bounty for the capture of Zimmerman, the Florida neighborhood watch captain who shot and killed Martin, an unarmed teenager, last month. "An eye for an eye, a tooth for a tooth," Black Panther leader Mikhail Muhammad said Saturday at a rally in Sanford, where Martin was killed Feb. 26, according to Fox News. Zimmerman has claimed he shot Martin in self-defense, but the New Black Panthers are calling for mobilization of 10,000 black men to capture Zimmerman, who has gone into hiding, the Orlando Sentinel reported. "He should be fearful for his life," Muhammad said. "You can't keep killing black children." According to the website of the Southern Poverty Law Center, the New Black Panthers "is a virulently racist and anti-Semitic organization whose leaders have encouraged violence against whites, Jews and law enforcement officers." The group was founded in Dallas in 1989 and believes black Americans should have their own nation, according to the SPLC. Zimmerman shot Martin as he returned to his father's house from a store where he had bought candy. Zimmerman told a 911 dispatcher that Martin was acting suspicious and told police that he was attacked by Martin. Sanford police say they were advised by prosecutors that they did not have enough evidence to charge Zimmerman.
