Tennessee Bureau of Investigation agents investigated an officer-involved shooting that happened June 16 in White House.
During the investigation, agents found information that Samantha Rediker, 34, of Cedar Hill, pointed a gun at two White House police officers.
The gun was later identified as a BB gun.
The officers responded to a reported domestic situation that involved Rediker and her wife at the Motel 6 on Hester Drive.
The officers told Rediker to drop the gun, but she did not, so they shot her.
Rediker was treated for her wound and released.
A Robertson County grand jury returned indictments Sept. 20 that charged Rediker with two counts of assault.
She was arrested Wednesday and booked in at the Robertson County Jail on $7,500 bond.
