MEXICO CITY (AP) — The former head of Mexico's state oil company was arrested Wednesday in Spain on a international warrant issued by Mexico, authorities said.

Mexican Attorney General Alejandro Gertz Manero told Radio Formula that Emilio Lozoya was arrested in the southern port city of Malaga.

Lozoya was director of Pemex between 2012 and 2016 during the administration of former Mexican President Enrique Peña Nieto.

Mexico issued international arrest warrants against Lozoya last year as a result of corruption investigations, including into his alleged ties to Odebrecht, the Brazilian construction company that secured contracts across Latin America through a network of bribes.

Officials are also investing Pemex's purchase of a fertilizer plant in 2015 at an allegedly inflated price.

Lozoya has repeatedly denied wrongdoing.
