A Cambridge man stole the identity information of five people and planned to use that information to raid nearly $1 million from college savings funds they had established, according to charges filed in federal court Friday. US Attorney Carmen M. Ortiz’s office said Mohammed Gisan, 26, was charged with five counts of identity theft. While employed by Upromise Investments, authorities said, Gisan used company records to obtain personal information about customers. When Gisan’s employment at Upromise ended in May 2011, he planned to use that access to steal a total of $965,274 from the accounts, Ortiz’s office said. If convicted of the charges, Gisan could face five years in prison.
