Germany's financial services regulator BaFin said Wednesday it will examine Invesco AIM Management Group Inc.'s (IVZ) announcement on its stakeholding in German truck maker and engineering group MAN SE (MAN.XE).

"We will examine the incident and see whether there are indications for market manipulation," a BaFin spokeswoman told Dow Jones Newswires. She declined to comment on the possible timeframe of the investigation.

Earlier Wednesday, MAN said Invesco corrected a statement made last week following "a calculation error," noting the U.S. investment firm's stake was actually less than 3% and not 10.4% as announced Sept. 30.

The initial announcement suggested Invesco had become MAN's second-largest shareholder after Volkswagen AG (VOW.XE), which holds a stake of 29.9%. The announcement sparked market speculation that Invesco could help Volkswagen prepare a takeover of MAN.
