Pipe bombs sent to American Century and Janus Capital may be tied to an unidentified person known as "The Bishop," said Fred Burton, vice president of counterterrorism and corporate security of private intelligence company Strategic Forecasting Inc. in a newsletter to the firm's clients, which include hedge funds, investment firms, oil and gas companies and government agencies
The pipe bombs — delivered to Kansas City, Mo.-based American Century Investments on Jan. 31 and to Janus Capital Group subadviser Perkins, Wolf, McDonnell and Co. in Chicago on Feb. 1 — were sent from Rolling Meadows, Ill., according to a letter to Strategic Forecasting clients. The device sent to American Century contained a note that read "Bang! You're dead," according to the newsletter. Mailroom employees called police, who defused it.
The Bishop has been sending threatening letters to financial services companies since at least 2005, according to Strategic Forecasting's newsletter. Earlier letters to financial services companies demanded that the targeted companies act to move specific stocks to a predetermined price, frequently $6.66. The letters initially threatened random violence and kidnapping but have become more specific in their mention of package bombs.
Mr. Burton warned clients in the newsletter that the devices, although not rigged to explode, were still dangerous. "Static electricity or even a transmission from a handheld radio could have set it off under the right conditions," he said in the letter. "Therefore, any such device should not be dismissed as harmless."
Wanda Shipp, a spokeswoman for the U.S. Postal Inspection Service, which is leading the investigation, said she could not comment on the investigation.
A spokeswoman at Janus and a spokesman at American declined to comment. Mr. Burton did not return calls requesting comment.
