SANTA ANA, Calif. — A human-trafficking case against a Saudi princess in California has been dismissed.

The surprise announcement came Friday as 42-year-old Meshael Alayban was to have been arraigned in Orange County Superior Court on a charge that could have brought as many as 12 years in prison upon conviction.

The charge was filed this summer after a Kenyan maid alleged the princess had taken away her passport and forced her to work long hours without pay.

Prosecutors now say further investigation did not corroborate the allegations.
