Immigration officials apprehended a pair of Ecuadorian brothers who'd been residing in Miami for more than a decade in the midst of heated and long-running litigation.

U.S. Immigration and Customs Enforcement arrested Roberto and William Isaías on Feb. 13. ICE spokesperson Nestor Yglesias said the brothers were “unlawfully present” in the U.S., and have been “transferred to ICE's Enforcement and Removal Operations” for deportation proceedings following their arrest. Yglesias added the pair is “in agency custody pending removal proceedings.”

The detainment of the Isaías brothers marks the latest twist in a legal saga that's spanned a decade. In 2009, Ecuador accused both brothers of fraud in a civil lawsuit filed in Miami-Dade Circuit Court. The complaint alleged the pair had embezzled $661 million from Filanbanco, an Ecuadorian bank where Roberto and William served as executive president and executive vice president, respectively, until 1998. The Ecuadorian government had injected more than $1 billion into Filanbanco to keep it solvent in the midst of an international financial crisis during the late 1990s. In the filing, Ecuador argued the brothers made off with money that'd been intended to preserve the bank's health.
