A senior executive at Flow Traders NV, Europe’s biggest market maker in exchange-traded funds, left the firm amid an internal investigation into alleged incidents at a company party in a Swedish ski resort, people familiar with the matter said.

Thomas Wolff, who was chief technology officer at Amsterdam-based Flow Traders and a member of its management board until March, is at the center of the review, the people said. The alleged incidents took place that month at the Copperhill Mountain Lodge in the town of Are where dozens of Flow Traders employees had gathered for the firm’s annual party, according to the people, who requested anonymity as details aren’t public.
