A former teller at a Baton Rouge credit union was sentenced to 10 months in federal prison after she was convicted of defrauding it out of more than $500,000 over four years, U.S. Attorney Walt Green said Thursday.

In addition to prison time, Whittney M. Lathan was sentenced to serve a five-year term of supervision, pay $508,182 in restitution and forfeit $309,350 in assets.

Lathan was convicted Sept. 3 on bank fraud in a scheme to defraud Dow Federal Credit Union out of more than half a million dollars while she was employed as a teller between Jan. 2, 2009, and June 29, 2013.

The FBI investigated the case, and Assistant U.S. Attorney Rene Salomon prosecuted it.
