American Tower Corp. yesterday filed a lawsuit against Jide J. Zeitlin, founder of Keffi Group Ltd. and Independent Mobile Infrastructure, claiming Zeitlin had impersonated American Tower's chief executive James Taiclet in sending a negative CNN.com article Zeitlin had planted about American Tower to two of the company's key investors.

"American Tower said Mr. Zeitlin had previously acknowledged misappropriating Mr. Taiclet's identity and sending the e-mail message via CNN.com, but had refused to cooperate with its efforts to further investigate his actions," Reuters reports. "The company, based in Boston, is suing for defamation, computer fraud and other claims and is seeking damages."
