New York City Mayor Michael Bloomberg.

NEW YORK (CNN) - Two men have been accused of stealing money from the personal bank account of New York Mayor Michael Bloomberg, the Manhattan District Attorney's office announced Tuesday.

Charles Nelson, 31, was charged with grand larceny and identity theft after stealing $10,000 from the billionaire in an online transaction on May 11, the district attorney's office said in a news release. The defendant allegedly transferred the money into an e-trade account and then withdrew it using a debit card.

The release said Nelson was arrested in Newark, N.J., after authorities discovered a computer, documents and two guns linking him to the crime. He was to be arraigned in New Jersey on weapons charges and then transferred to the district attorney's office.

Authorities discovered the withdrawal after being alerted to a different transfer from Bloomberg's account allegedly attempted by Odalis Bostic, 24, of Elizabeth, N.J.

Last June, Bostic allegedly attempted to deposit two forged checks from the mayor's financial manager, Geller & Company, into Bostic's company bank account. The defendant allegedly set up the Laderman Development Company, located in Elizabeth, N.J., and wrote two checks, for $190,000 and $230,000 respectively.

Barbara Thompson of the district attorney's office said the size of the amounts and the checks' fraudulent appearance raised their suspicions and an investigation revealed they were forgeries. Bostic was arraigned Tuesday in New York State Supreme Court and is being held on $10,000 bail. His next scheduled court date is Oct. 18.

According to Thompson, authorities are unsure whether the alleged crimes are connected. If convicted, each man could face up to seven years in prison.
