Federal prosecutors say a North Carolina woman submitted more than $600,000 in false Medicaid claims and used the money to buy a Bentley, a Hummer and spa services.

Sarah Lavonne Willis of Charlotte was indicted Wednesday on allegations that she billed a state medical assistance program for behavioral therapy services she didn't provide. Prosecutors said the scheme lasted from 2007 until this year.

Court documents say Willis used proceeds to buy a 2006 Bentley Continental Flying Spur, a 2007 Hummer H2, spa services and luxury hotel lodging.

If convicted, she faces a maximum penalty of 10 years in prison and a $250,000 fine for each of 27 counts.

An attorney for Willis declined comment. Authorities say she is in custody on unrelated charges.
