"A Saudi Arabian fan told us that, in the evening of June 24, he gave USD $120,000 and €110,000 to an unknown person for organising a flight from Moscow to Volgograd. The person then escaped with the money," the source said.

A criminal investigation has been opened into the case.

Saudi Arabia beat Egypt 2-1 in Volgograd on Monday after both teams had been eliminated from the World Cup.
