Apolinar Mena, a state-level government official embroiled in a corruption scandal with the Mexico unit of Spanish builder OHL resigned on Sunday, local media reported.
Mena, who was the Transport and Communications Minister for the State of Mexico, resigned and was fined 189,000 pesos (US$12,603), media reported, more than a week after the release of recordings, in which OHL México executives are heard offering him a free hotel stay.
Mena has said that he did not accept the offer and paid for his own stay.
In the other recordings, OHL México executives are heard discussing overcharging the government of the State of Mexico for public works. The company said that the recordings are of some of their employees, but that the audio had been manipulated.
Representatives for the State of Mexico government could not immediately be reached for comment.
