David Tresch, Mayer Brown’s former chief information officer, was arrested on federal charges Thursday alleging that he pocketed hundreds of thousands of dollars for vendor work never performed at the firm.

The former executive approved nearly $8 million in payments for information technology services between 2004 and 2008 for work done by an unnamed Chicago suburbs-based vendor, the Chicago Tribune reports. The criminal complaint says the vendor paid Tresch and his wife nearly $1.3 million during that time period.

Despite orders to stop using the vendor in February 2011, Tresch approved invoices for work that was never performed, and reimbursed the vendor about $980,000 between May 2011 to May 2012. The complaint says Tresch received more than $850,000 from the same vendor during that time, the Tribune reports.

While Mayer Brown wasn’t identified in the complaint, the firm confirmed Tresch’s employment since 2004, according to the Tribune, which also notes that the firm said it fired him in late June after an internal investigation and referred the matter to federal prosecutors.
