Eric Prydz Sues Alleged Calvin Harris Fraudster, Thomas St. John

After Calvin Harris filed a $22.5 million fraud complaint against his former financial advisor, Thomas St. John, Eric Prydz has filed a lawsuit of his own for $269,000.

Those with a finger on the pulse of the EDM industry will recall that Calvin Harris is seeking $22.5 in damages from his former financial advisor, Thomas St. John. Now, Eric Prydz has filed a lawsuit against the same defendant, this one for $269,000.

Unlike that of Harris, Prydz’s camp claims that St. John flat-out stole money from the Swedish DJ and producer. “TSJ is supposed to be trustworthy and reliable, and … should be acting in the best interests of his client,” reads part of the complaint. “TSJ, however, proved to be none of those things. Instead, he is a fraud who not only abuses the trust of his clients, he takes money from them without their knowledge or authorization for his personal use and benefit.”

Prydz allegedly entered into a business relationship with St. John in 2012, and in summer 2025, Prydz’s team uncovered discrepancies indicating that St. John had collected $219,000 in unauthorized payments from him. Email verbiage included in the lawsuit indicates that in September 2025, the “Opus” artist’s manager terminated their deal and forbid St. John from making any further transfers from his account.

St. John allegedly agreed to prepare and file one final tax return for Prydz. According to the complaint, St. John failed to follow through by the deadline, forcing Prydz into delinquency. Then, in defiance of Prydz’s manager’s request, he transferred another $50,000 from his account in October 2025.

“TSJ owed Prydz a duty of confidentiality,” reads the lawsuit. “TSJ breached his duty of confidentiality to Prydz when he used Prydz’s confidential financial information to take more than $250,000 from Prydz without permission and authority, including $50,000 after being told — in writing — he was ‘no longer authorised to make any payments, or remove any funds from any of [Prydz]’s personal or business accounts or to perform any services for [Prydz] without express written notification from either [Prydz] or [his manager].’”

On top of the $269,000 in misappropriated funds, Eric Prydz’s team is also seeking punitive damages as well as legal fees and court costs.
