The controversial incident took place after a friendly game between Mexican champions Tigres UANL and American side Houston Dash last Saturday.

Right after the game, Houston Dash midfielder Sofia Huerta went into the crowd to greet fans and take pictures with them.

While she was taking a selfie with the spectators a man standing behind her appeared to place his left hand on her breast.

The embarrassing moment was captured on camera, forcing the Mexican club to open an investigation in an attempt to identify the man who they think intentionally groped Huerta’s breast.

The Tigers apologized to Huerta and her family for the "regrettable experience" she suffered.

"Once the so-called fan has been identified, he will be prohibited for life from entering any of our facilities and any women's or men's matches," the club said in a statement.

"At Tigres, we are fully committed to eradicating in our stadium and in our community any form of harassment or situation that violates human dignity or seeks to intimidate, degrade or offend women.

"As a result of the events that took place on Saturday, in which a so-called fan presumably violated the dignity of the Houston Dash player at the end of the game, we have decided to take action regarding this action. We will be filing a lawsuit against whoever was responsible for this event."
