A 17-year-old girl was found bound and gagged in the backseat of a car Monday night in Carlsbad and authorities say her abductors were her father and sister.

Officers stopped the car near the Cannon Road exit off I-5. 

Investigators learned the girl's 67-year-old father and 21-year-old sister, abducted her with the intent of taking her to a drug rehabilitation center in Mexico.

The girl was taken into protective custody. 

Criminal charges are pending against the father and sister.
