Swiss Police have confirmed a bomb threat has been made at the FIFA Congress in Zurich.

Delegates from the 209 associations were told they were not permitted to remain in the Congress Hall during a 90-minute lunch break.

A Zurich police spokesman told Bloomberg: "We can confirm the receipt of a bomb threat."

Earlier, two pro-Palestinian protestors were ejected from the Congress hall after making their way inside, while a demonstration calling for Israel to be ejected from FIFA continued outside.

Delegates returned to the main Congress Hall at around 12.30pm UK time.

Meanwhile, Britain's Serious Fraud Office says it is assessing "material in its possession" relating to allegations of Fifa corruption.

It said it stands ready to "assist ongoing international criminal investigations" related to Fifa corruption.

The Serious Fraud Office would not comment on the material it is holding. Several British-based international banks, however, are mentioned in the US indictment of Fifa officials.

The fraud office is responsible for handling complex, major investigations into financial wrongdoing.

The announcement stops short of announcing that proof of criminal activity has been found.
