Documents have been taken from the Paris headquarters of the French Football Federation (FFF) as the Swiss criminal investigation into former FIFA President Sepp Blatter continues.

The FFF consented to the search, according to the office of Switzerland’s Attorney General, which also claimed to have received cooperation from the French Financial Prosecution Office.

It reportedly related to the alleged "disloyal" payment of CHF2 million (£1.5 million/$2 million/€1.8 million) made to France's UEFA President Michael Platini by Blatter in 2011.

Criminal proceedings were opened against Blatter last September 

Both men have since been banned from all football-related activities for six years by the FIFA Ethics Committee.

Each is currently appealing the decision to the Court of Arbitration for Sport in Lausanne.

They claim the payment relates to a verbal deal for additional salary owed to Platini for working as Blatter’s Presidential advisor between 1999 and 2002.

"The Office of the Attorney General of Switzerland required the mutual legal assistance of the French judicial authorities in connection with the criminal proceedings against Mr Joseph Blatter," a statement explained.

"Pursuant to that request for mutual legal assistance of January 14, 2016 and in close coordination with the Office of the Attorney General of Switzerland, the French Financial Prosecution Office proceeded to a search of the offices of the French Football Federation (FFF) in Paris with the latter’s consent,

"The Office of the Attorney General of Switzerland was present during the search.

"Documents were seized in connection with the suspected payment of CHF 2 million that is inter alia the subject of the proceedings.

"The Office of the Attorney General of Switzerland thanks the French judicial authorities for their valuable support in this matter."

It follows the election last month of Gianni Infantino as Blatter's successor at the FIFA Congress in Zurich on a vow to "restore the image" of the under fire world governing body.

Blatter is also accused of signing an "unfavourable" contract with the Caribbean Football Union and former FIFA vice-president Jack Warner.

Ethics judges ruled that Blatter broke rules on conflicts of interest, breach of loyalty and offering gifts.
