FRISCO (CBSDFW.COM) – Two Frisco children who have been missing for two weeks have been found in Las Vegas.

Frisco Spokesman Greg Barnett confirms 6-year-old Sarah Alexis and 2-year-old Gavin Anton Dobry were found Friday and that their mother, Nicole Dobry, was arrested by the  U.S. Marshals Service.

The children were reported missing on July 13 by their father, Dr. Chris Dobry, after their biological mother did not return the children to him.

The father has primary custody of the children.

Police were afraid that Nicole Dorby might have been  trying to leave the U.S. with the children, taking them to Vietnam, her country of origin.

Barnett says Nicole Dobry faces two charges of interference with child custody, a state jail felony.

Barnett says both children are safe and will be reunited with their father.
