HOUSTON (AP) — A seventh person convicted in a $45 million health care fraud scheme based in Houston has been sentenced to prison.

A federal judge in Houston on Monday ordered 41 months in prison for 56-year-old Tony Nnonso Obi. The naturalized U.S. citizen from Nigeria in August pleaded guilty to conspiracy to commit health care fraud and to money laundering.

Prosecutors say Obi was affiliated with an assisted living facility and sent some residents to City Nursing Service of Texas Inc.

Authorities say City Nursing owner Umawa Imo paid Obi more than $1 million in the Medicare and Medicaid scheme. Imo last year was sentenced to more than 27 years in prison for running the scam.

An eighth person convicted in the fraud case awaits sentencing.
