A 22-year-old Macon woman is in custody and is charged with the Thursday armed robbery at the Subway, located at 630 North Ave., according to Macon police.
Jackequina Carr is being held at the Bibb County jail, according to a police news release.
Warrants have been signed for two other people, but police officers said they are withholding the names because their release would compromise the investigation.
Investigators still are trying to identify a suspect in connection with the Wednesday Subway robbery on Vineville Avenue.
Anyone with information about either robbery is asked to call the police at 751-7500 or Macon Regional CrimeStoppers at (877) 68-CRIME.
