In the press statement, he was referred to only as “Enrique ‘P'”, in line with Mexican policy of not identifying those accused of crimes. But a prosecutor’s office confirmed that it was Peña Nieto.

Peña Nieto ruled Mexico from 2012 to 2018 and has lived in Spain ever since. When the Financial Intelligence Unit indictment was announced last month, Peña Nieto wrote in his Twitter account that his money had been obtained legally.

No charges have been filed.

Last month, the unit’s head Pablo Gomez said a company run by Peña Nieto’s family had “a symbiotic relationship” with a company that received about $500 million in government contracts while he was president.

Tuesday’s announcement didn’t add much detail, but did call Spanish construction company OHL, which has a subsidiary in Mexico, involved in a number of allegations against Peña Nieto. It said charges in that investigation could come in the coming months.

Gomez had also said that Peña Nieto received money transfers from a relative, apparently connected to two companies — his family and one receiving government contracts — for about $1.3 million after his departure.

In 2016, the Mexican National Banking and Stock Commission fined OHL the equivalent of more than $4 million for alleged accounting irregularities, the highest fine the agency has ever imposed.

OHL’s Mexican subsidiary said at the time that it has “always acted transparently and with best business practices.”

A year earlier, OHL was embroiled in a scandal in Mexico over possible corruption related to highway contracts. Footage has surfaced that allegedly showed company executives discussing bribes and making plans to increase road tolls.
