A former University employee has been charged with operating a kickback scheme that brought in tens of thousands of dollars over eight years.

The employee, George Dobuzinsky, was charged with conspiracy and fraud by federal prosecutors on Monday. The prosecutors claim that Dobuzinsky, who was a project manager for the University, used his position to receive tens of thousands of dollars in kickbacks from vendors for audio/visual work at Yale. In exchange, the prosecutors said, he would reward contracts to the vendors.

Dobuzinsky’s fraud is reported to have run between 2005 and 2013.

“Mr. Dobuzinsky did not steal anything from Yale,” said attorney Norm Pattis, who represents Dobuzinsky. “He worked harder than any two other employees in his unit.”

According to Pattis, the total amount in question was $122,000. Dobuzinsky is also charged with accepting steakhouse certificates and electronic equipment from the vendors.

Dobuzinsky, who plead not guilty in Bridgeport court, was released on $300,000 bail.

He has been charged with one count of conspiracy to commit wire fraud and three counts of honest services wire fraud, each of which can lead to 20 years in prison.
