Two men were charged in unrelated fraud cases yesterday.  The common denominator? Michael R. Bloomberg, the billionaire mayor of New York City.

The first man, Odalis Bostic, is accused of trying to steal $420,000 from the mayor through two forged checks in the name of Bloomberg’s financial manager.

Bostic attempted to deposit the two checks, both issued from Bloomberg’s personal account with Bank of America, into accounts he established with Sovereign Bank and PNC. Due to the large amounts of the checks, both banks put holds on the checks and discovered the fraud.

Another instance of attempted fraud against the mayor was discovered during the investigation of Bostic. Charles Nelson was charged with an unrelated case of fraud citing his transfer of $10,000 from Bloomberg’s personal account to an E*Trade account established in his name.

Authorities found a computer, various documents and two guns on Nelson when he was arrested in Newark, New Jersey.
