Benin coach Reinhard Fabisch says he was asked before the Squirrels' Africa Cup of Nations match against Mali if he would help fix the game's outcome.
Benin lost the Group B match 1-0 after conceding a penalty at the start of the second half.
"He wanted to find out from me if there was any possibility of manipulating the match," Fabisch said of the approach.
"I told him: 'Look, you have two minutes to leave the hotel or I will call the police'."
Fabisch was approached by a man who spoke to him at the team's hotel on Saturday, two days before Benin's opening match against Mali in Sekondi.
"I cut him short and told him to leave. It doesn't help football.
"I assume that if someone approaches you like that, then they have that (money) in mind."
Subsequently Fabisch warned his players to tell him if they were approached.
Benin next play Ivory Coast in Sekondi on Friday.
