Watts, 43, of Tullahoma, was arrested on a charge of violation of parole, Detective Lt. Pat Mathis of the Shelbyville Police Department said. He is being held without bond at Bedford County Jail.
The new charge stems from an unspecified 2006 conviction for which Watts is still on parole, Detective Sgt. Brian Crews said.
Staff members at Thomas Magnet School said Watts threatened to "go and get an AK-47 and come up in here and shoot everybody and then kill myself" Wednesday. He and his girlfriend, the mother of a student, had been denied permission to check the pupil out early for a birthday lunch. The student's biological father had not signed a letter of permission for the child to be checked out early, SPD Sgt. James Wilkerson said.
Witnesses said Watts also said he has a doctor's appointment Wednesday, Dec. 19 and if diagnosed with cancer he would "return to Thomas School and take care of business."
Watts is a convicted felon and does not have permission to own a gun; he was not armed when at the school. The felony convictions are for burglary and possession of marijuana in Coffee and Davidson counties, Mathis said, and did not involve violent acts.
Police had charged Watts last Wednesday with filing a false report; he posted $10,000 bond.
Thomas Magnet School was under guard Monday morning with multiple police officers posted at entrances as children arrived.
