Devore also provided inside information concerning Dell suppliers including Western Digital and Seagate, according to court filings.

Fleishman was arrested Thursday on wire fraud and conspiracy charges.

Also arrested Thursday were Mark Longoria, formerly a supply chain manager with Advanced Micro Devices (AMD); Walter Shimoon, a senior director of business development with Flextronics International; and Manosha Karunatilaka, an account manager with Taiwan Semiconductor Manufacturing Company (TSMC), the DOJ said.

All three are facing wire and securities fraud charges.

AMD's Longoria made more than $200,000 during a two-year period, prosecutors say.
