ORLANDO, Fla. (AP) — The mother of a missing Florida toddler is back in jail.

Sheriff's deputies say Casey Anthony was arrested for a third time Monday while visiting her case manager. The new charges relate to alleged theft from a friend.

The 22-year-old has been in and out of custody since 3-year-old Caylee Anthony was reported missing in mid-July. She hasn't been charged in Caylee's disappearance, though detectives say lab tests show Caylee's decomposing body was in Anthony's car.
