Former Nigeria Captain, Nwankwo Kanu, has been robbed of Â£8,000 (about N4million) in the city where Super Eagles are to play their opening Group D match against Croatia on June 16.
TASS Russian News Agency reported that the money was stolen from Kanuâ€™s luggage by the baggage handlers at the Khrabrovo Airport.
â€œWhen Kanu discovered that the money was stolen when he got to his hotel, he promptly made a report and the two airport staff were detained on suspicion of stealing the money from the Nigeria legend.â€
Lieutenant Colonel Irina Volk, spokeswoman for the Russian Interior Ministry, said the loaders were dealing with the baggage from a London to Moscow flight.
â€œThe stolen cash was removed (from the loaders) and will soon be returned to the ownerâ€, she said.
The loaders, aged 30 and 36, face criminal investigation and could be sent to jail for up to six years.
Kanu played alongside ex-Manchester United and England star Wes Brown in a FIFA legends team against a Russian legends side.
The ex-Arsenal man, a former Nigerian international, did not mention the theft in speaking to the media in the Baltic city.
â€œKaliningrad is a very nice city with very nice people,â€ said Nwankwo Kanu.
â€œ Nigeria will be a big surprise, for sure. We have good young and talented players; they are hungry for victories and want to do well â€“ for themselves and for the country,â€ Kanu was quoted as saying to UKâ€™s Mirror newspaper.
