"The piece is a fabrication, because it belongs to none of the pre-Hispanic cultures in Mexico," the foreign ministry and the National Institute of Anthropology and History (INAH) said in a joint statement.

It said INAH experts had determined it was a fake because it did not match the style of the period it was supposedly from, and that the Mexican embassy had informed French authorities.

The 165.5-centimeter (5.4-foot) god, with legs slightly bent and wearing sandals with long leather straps, was said to be from the Maya late classical period (550-950 AD).

The piece was part of a private collection of some 200 sculptures belonging to Swiss industrialist Henry Law.

The piece sold for 2,912,000 euros, the highest amount ever paid for an item of its kind, by an anonymous European buyer.

It was the most expensive item at the auction, which fetched a total of 7,4 million euros, according to a statement from the Drouot auction house.

The auction also included an Olmec figure from 300-100 BC that set a record by selling for 900,000 euros ($1.2 million) and a belt used for a pre-Hispanic ball game, which fetched 283,500 euros.
