CINCINNATI (AP) -- A former Cincinnati city employees union president accused of embezzling more than $750,000 from the union since 2005 has pleaded guilty to a federal wire fraud charge.

Court documents show 51-year-old Diana Frey (FREYE) pleaded guilty Wednesday in federal court in Cincinnati.

Frey's telephone number was not immediately available. Her attorney declined comment

Federal prosecutors say Frey fraudulently transferred money from the Cincinnati Organized and Dedicated Employees union through checks, ATM withdrawals, credit cards and wire transfers to her bank accounts or for her personal benefit.

Prosecutors also say Frey allegedly misrepresented union finances to other union officers and members. The union represents about 800 members.

Frey could be sentenced to up to 20 years in prison and fined up to $1.5 million.
