Nigeria's anti-corruption agency says it is investigating current and former leaders of the country's soccer federation.

Economic and Financial Crimes Commission spokesman Femi Babafemi Tells The Associated Press that the investigation centres on former president Sani Lulu and former vice-president Amanze Ugbulam.

Babafemi said Wednesday that investigators are also looking at former technical committee member Taiwo Ogunjobi and current general secretary Bolaji Ojo-Oba.

Babafemi made his comments after President Goodluck Jonathan backed down on his threat to suspend the federation after Nigeria's poor performance at the World Cup.

FIFA had been set to sanction the country if Jonathan followed through on his threat.
