A 47-year-old Greenville man was arrested early Wednesday after police say he threatened to kill his estranged wife if she would not give false testimony on his behalf.
Norman Henry Shackley is charged with extortion, obstruction of justice and intimidating a witness.
Shackley's latest charges stem from a Dec. 23, 2012, arrest in which police said he impersonated a law enforcement official after getting into an altercation with a man at Ample Mini Storage on Arlington Boulevard.
Shackley told the man he was a federal officer, displayed a gold-colored badge and threatened to arrest him. He received a $100,000 secured bond in that case.
Shackley was in jail Wednesday under a $400,000 secured bond.
