FIFA is investigating a BBC News report that journalists from the broadcaster were arrested and put in prison when reporting on Qatar's World Cup workers.
The welfare of migrant workers involved in building facilities for the tournament, which will be held in Qatar in seven years' time, has come in for intense scrutiny ever since the Gulf state was awarded the right to host the tournament in 2010.
BBC News reporters were "invited to Qatar by the prime minister's office to see new flagship accommodation for low-paid migrant workers," according to a report from Doha on the corporation's website.
The report alleges the journalists were surrounded by eight cars and "a dozen security officers," then had their equipment taken from them, before being taken to a local prison in the early hours of the morning where they would spend two nights before being released.
The journalists were then reportedly allowed to join up with the organised press trip that they had intended to attend.
A FIFA statement said: "Any instance relating to an apparent restriction of press freedom is of concern to FIFA and will be looked into with the seriousness it deserves."
Qatar's minister of labour Abdullah al-Khulaifi said: "Qatar is an open country forever, since ever. The shortcomings that I am facing, the problems I am facing, I cannot hide. Qatar is open and now with the smartphones, everyone is a journalist."
Earlier this month, members of a German television crew were arrested and detained in Qatar while filming construction sites for the 2022 World Cup in the Gulf state, the station's parent company revealed.
