In another example of the scheme, in February 2013, according to the indictment, Mr. Allison created a bank card for one account. That May, at a Chase branch on Flatbush Avenue, Mr. Phillips turned in fake power of attorney documents giving him control of the account. The same day, prosecutors said, Mr. Phillips withdrew through a teller $49,929.91 — everything that remained — from the account.
JPMorgan Chase has already faced accusations of fraud among staff members this year. In April, an investment adviser, Michael Oppenheim, was charged in Federal District Court in Manhattan with stealing $20 million from seven of the bank’s clients.
Also in April, another employee, Peter Persaud, who worked at a Chase branch in Brooklyn, was accused of selling customer data — including account numbers, Social Security numbers, addresses and dates of birth — to an informant and an undercover officer. Mr. Persaud was charged with fraud and identity theft in Federal District Court in Brooklyn.
Lauren Ryan, a spokeswoman for JPMorgan Chase, said the company has been “working closely with the authorities and the Social Security Administration” in the current fraud case.
The four men listed in the current indictment have been charged with conspiracy, grand larceny and falsifying business records.
On Monday, Mr. Allison was arraigned before Justice Cassandra M. Mullen in State Supreme Court in Brooklyn. Mr. Zion, the prosecutor, said that Mr. Allison searched for and maintained the targeted accounts, and issued and used some of the cards.
He had told Chase investigators that he had looked for high-value accounts, issued and used the A.T.M. cards, sold some of the cards and account data, and worked with Mr. Francis on the scheme, Mr. Zion said. Also, he had logged onto the Chase system with his co-workers’ credentials when they were away from their desks, according to Mr. Zion.
Prosecutors requested $100,000 bail; Justice Mullen released him on $25,000 bond. Mr. Francis and Mr. Desrameaux were arraigned earlier this month.
Mr. Allison’s lawyer did not immediately respond to a request for comment. Douglas Rankin, the lawyer for Mr. Francis, said that his client denied the allegations, and that he no longer worked at Chase and “left on his own before this became an issue.” David Walensky, the lawyer for Mr. Desrameaux, said his client denied involvement in the scheme.
Mr. Phillips is still at large, according to a news release from the district attorney’s office.
