An investigation into alleged corruption by FIFA officials has led to property seizures in the Swiss Alps.

US Attorney-General Loretta Lynch warned investigators are expecting to file more charges after the football body’s largest scandal in its history led to the arrest of seven officials in May.

“Based upon cooperation [with Swiss authorities] and new evidence, we do anticipate pursuing additional charges against individuals and entities,” Lynch said at a Zurich press conference.

Lynch’s Swiss counterpart Michael Lauber told reporters at the same press conference the investigation was still in its early stages but authorities had already gathered formidable evidence – including 11 terabytes of electronic data.

“Where proportional and needed, financial assets have been seized, including real estate, for example flats in the Swiss Alps,” Lauber said.

“At this point I would like to emphasise that investments in real estate can be misused for the purpose of money laundering.”

Those arrested included English-born Greek Cypriot businessman Costas Takkas.
