California police have issued an Amber Alert for a 10-month-old boy believed to have been taken by his mother from the Children's Hospital of Orange.

Officials believe Alakahi Thompson was taken by his mother, Ida Marybel Torres, on Wednesday night. Alakahi's father has legal custody of the child.

Alakahi is described as "at risk" because he is being treated for possible pneumonia, MyFOXLA.com reports.

Torres also had two of Alakahi's siblings with her, although it was unclear if they also are considered kidnap victims. They were not identified nor listed in the Amber Alert, MyFOXLA.com reports.

Torres is described as a 5-foot-4, 125-pound Hispanic woman with brown hair and eyes. She is believed to be driving a rented silver Chrysler Sebring with the California license plate 6AHA682.

Torres may be headed for Kentucky, where she is a resident, MyFOXLA.com reports.

Anyone with information as to the child and Torres' whereabouts are asked to call the Orange County Sheriff's Office at 714-744-7444.
