Grisel Ramirez was arrested for allegedly trying to kidnap a newborn baby from the Garden Grove Medical Center in Garden Grove, California.
According to the Daily Mail, Ramirez disguised herself in nurse scrubs and entered the medical center on Monday.
She reportedly told a new mom to take a shower before an exam. When the new mom went into the bathroom, Ramirez allegedly tried to steal the baby girl.
However, she got caught when hospital sensors, attached to the baby, detected the child, who was hidden inside Ramirez' duffel bag.
Lt. Jeff Nightengale said: "At this point we don't have a solid reason why she stole the baby. An alarm went off when the baby crossed an imaginary line in the hospital that set off a sensor."
Lt. Nightengale added that Ramirez "lived in the United States for 20 years, but we don't think that she's a legal resident of the country."
