Ancira was arrested in May 2019 as he boarded a plane to Canada in Spain’s Mallorca. Ancira led Altos Hornos de Mexico.
A court in Spain rejected Ancira’s attempt to avoid extradition in November.
Mexican prosecutors are investigating $3.4 million of money transfers from Altos Hornos de Mexico to a holding company connected with the former director of the state-owned oil company Petroleos Mexicanos. Emilio Lozoya, then Pemex’s chief, was also extradited from Spain and is cooperating with Mexican investigators.
The investigation into Ancira is related to the over-priced sale of a fertilizer plant to Pemex during the administration of President Enrique Peña Nieto.
