An investigation has been launched by the Egyptian FA (EFA) after it found that several trophies have disappeared from its headquarters in Cairo, including an original African Cup of Nations.

Egypt received the prize after winning the 2010 edition of the tournament, so claiming that particular incarnation of the trophy for a third time.

The trophy, whose style was first used in 2002 after Cameroon were awarded the previous cup having won it three times, was given to the EFA by the Confederation of African Football (Caf) after triumphs in 2006, 2008 and 2010.

On Friday, the EFA – whose media director confirmed the trophy’s loss to the BBC – said it had opened an investigation into the loss of the various trophies.

“As the Egyptian FA is currently developing the main headquarters, including changing the entrance to a small museum of Egyptian football, the management was shocked by the disappearance of some old trophies from the storeroom,” said the EFA in a statement.

After the EFA headquarters were attacked in 2013, various trophies – including the Nations Cup – were moved to a storeroom.

However, local officials only searched for them recently after the decision to renovate the EFA’s entrance so that Egypt’s multiple football cups could be displayed there.

The storming of the EFA by angry fans seven years ago during violence in Cairo is now a focal point as officials try to determine when and how the trophies were taken.

“The EFA is now investigating the trophies’ disappearance to determine if those old trophies were saved after the building was burned … or if they were lost when the building was exposed during this incident,” the EFA added.

Caf regulations state that a team that wins a particular incarnation of the Africa Cup of Nations trophy three times will own it for good.

Ghana was the first team to win the trophy three times, in 1978, while Cameroon then received the second version of the Nations Cup trophy after becoming the first country to win it on three occasions.

Under Caf rules, teams that win the Nations Cup receive a replica of the trophy on a permanent basis while they are allowed to keep the trophy for the two years in-between tournaments before handing it back.

The current trophy, whose style is still the same as the one won by Egypt, is in the hands of Algeria, who won the last Nations Cup title (in Cairo) last year.
