A woman was arrested by East Ridge Police after her former boyfriend said she and another man robbed him.

Onyx Johnson, 21, was charged with aggravated robbery.

In the incident on Sunday night, police were dispatched to 2281 Camp Jordan Parkway in reference to an armed robbery. Police were advised the victim was behind the suspect vehicle, a silver BMW X5, heading on I-75 north towards Hamilton Place.

The victim was instructed by dispatch to stop pursuit and return to the scene. Upon speaking to the victim, Marvin Douglas, he advised that he had agreed to meet with his ex-girlfriend, Ms. Johnson, at a motel on Brainerd Road behind the CVS to help her with bills.

Ms. Johnson called the victim back and asked him to meet her at the Motel 6 at 2281 Camp Jordan Parkway. When the victim arrived at the Motel 6 he met Ms. Johnson and they started walking to the front of the building when he observed an unknown black male exit Ms. Johnson's silver BMW X5, police said.

The unknown black male suspect walked up to the victim and said "Give me yo -------- money before I bust yo --------- ---------- -------." The suspect at that point pulled out a chrome revolver with a brown grip and pointed it at the victim's stomach while reaching into the victim's rear pocket and taking his wallet. The victim stated Ms. Johnson shouted "I knew I'd see your a-- somewhere and get you."

Police said Ms. Johnson got into the driver's seat of the vehicle and the unknown black male suspect got into the passenger seat and they went northbound on Wright Street with the victim following behind them. The suspect then went back towards Camp Jordan Parkway and got on I-75 north while the victim followed.

As police were on scene talking to the victim, a silver BMW X5 turned onto Camp Jordan Parkway going northbound. Officers ran the tag on the vehicle TN F6015V which came back to Onyx Johnson. The vehicle was stopped and Ms. Johnson was detained for further investigation.

Ms. Johnson gave a different account of the incident. She claimed she saw the victim behind the Motel 6 but had no idea who the unknown suspect was. Police later located the victim's wallet and miscellaneous contents on Wright Street.

Inside Ms. Johnson's wallet were nine newer $100 bills and six $20 bills. The denominations were consistent with what the victim reported was missing, police said.  Ms. Johnson was then taken into custody.
