DETROIT (AP) — A high-ranking United Auto Workers official is facing felony charges of embezzlement and fraud, and prosecutors say that several top union officials conspired to steal more than $1.5 million from the union.

Prosecutors outlined the charges against Edward N. Robinson in a filing Thursday in federal district court in Detroit. Robinson is president of a UAW council in Missouri.

According to the filing, Robinson and six other top UAW officials conspired since 2010 to embezzle funds through schemes such as submitting false vouchers for conference expenses.

The Detroit News, citing sources familiar with the investigation, said one of the unnamed union leaders, “UAW Official A,” is union President Gary Jones.

A UAW spokesman said the union takes any allegation of misuse of union funds very seriously.
