An infant is back safe with her mother after she was abducted on Sunday. An anonymous tip led police to 1-month-old Sarah Costello, who was found a Chicago diner on Monday.

The baby was checked out a hospital and then reunited with her mother.

Police are looking for the child's grandmother, 39-year-old Rosie Costello, for questioning in Sarah's disappearance.
