A U.S. federal court has sentenced a 40-year-old Nigerian man, Oluwaseun Adekoya, to 20 years in prison after his conviction on multiple fraud-related charges, including bank fraud conspiracy, money laundering conspiracy, and nine counts of aggravated identity theft.

Adekoya, who also went by the aliases “Santa” and “Legendary”, was found guilty following a three-week trial during which prosecutors detailed how he laundered more than $2 million.

According to U.S. authorities, Adekoya exploited his lawful permanent resident status to steal the identities of American citizens and execute a large-scale financial fraud operation.

Prosecutors said the scheme involved sophisticated methods aimed at defrauding banks and other financial institutions.

The conviction forms part of the ongoing U.S. efforts to clamp down on international cyber-enabled financial crimes.
