A Bulgarian national, Dimitar Vangelov, 27, who was arrested in Chicago in March, has pleaded guilty to financial crimes for credit, debit and gift card fraud.

The news was reported by CBS Chicago, informing that Cook County Judge, Nicholas Ford, has sentenced the Bulgarian to four years in prison, followed by two years of supervised release, according to the Illinois Attorney General's office.

US Secret Service and DEA agents, along with Chicago Police Financial Crimes Unit officers arrested Vangelov on March 27 after executing a search warrant at his apartment in the upscale Trump Tower on North Wabash Avenue.

Investigators initially found eight credit, debit and gift cards with Vangelov's name on them, but coded with someone else's bank account information, CBS Chicago reports, citing local authorities.

The attorney general's office later said investigators found a stash of hundreds of credit and gift cards encoded with stolen bank account numbers or credit card information from people overseas. Investigators also recovered several skimming devices used to steal bank and credit card information.

Vangelov was accused of re-encoding the credit and gift cards with stolen foreign bank account numbers, and was originally charged with identity theft.

Authorities further said he had no recordable income, but was living in the posh Trump Tower apartment, and driving a Mercedes Benz 500 series.
