Deutsche Bank's effort to spy on its critics was more extensive than previously disclosed, involving a plan to target as many as 20 people, including a number of investors, a detective involved in the affair told the Wall Street Journal.
In May 2009, Deutsche Bank said it had discovered efforts involving "questionable investigative or surveillance activities" directed by its in-house security department and outside contractors, including detective Bernd Buhner, to monitor people affiliated with the bank, the Wall Street Journal reported.
Buhner told the Wall Street Journal in an interview that he received a list of names in 2006 at a meeting with Deutsche Bank representatives that included members of the bank's legal department.
When questioned on the list, Deutsche Bank said investigators were unable to establish who compiled it. And in a July 22 news release, Deutsche Bank said the spying was directed by its security department but made no mention of its legal department's involvement, the newspaper reported.
A Deutsche Bank spokesperson said the list contained people and entities that might be linked to Michael Bohndorf, an activist investor the bank had already disclosed it spied on. The bank said the names on the list might have been able to provide information about Bohndorf's motives towards the bank and any connection he had to Leo Kirch, the former German media mogul who is suing Deutsche Bank for billions in connection with the collapse of his empire, the Journal said.
