A court in Brazil has blocked the assets of Olympic Broadcasting Services (OBS) following Rio 2016, it has been reported.
According to the Associated Press, the decision impacts "financial resources, trucks, equipment and furniture" used by the company during the Games.
Brazilian authorities want to secure compensation for "possible damages to workers hired by OBS", according to the legal decision.
Investigators have claimed that OBS needs to pay damages to "overworked" employees at both the Olympics and Paralympics, Associated Press said.
OBS, which is based in Spanish capital Madrid, was created by the International Olympic Committee (IOC) in 2001 to serve as the host broadcaster organisation for all Summer, Winter and Youth Olympic Games.
As host broadcaster the company is responsible for delivering the pictures and sound from every sports venue to viewers around the world.
It "produces and transmits unbiased live radio and television coverage", the OBS claims, using a feed called the international signal or world feed.
"In this role, OBS is responsible for developing a consistent approach across Olympic operations while at the same time optimising resources to continually improve the efficiency of the Host Broadcast operation," an explanation on the OBS website says.
"OBS does so to ensure that all IOC contractual obligations are fulfilled and the Games' Rights Holding Broadcasters (RHBs) are satisfied with the overall television production of the Olympic Games."
The Olympic Channel, launched after the Rio 2016 Olympics on August 21, is also based in Madrid.
An OBS statement said: "Olympic Broadcasting Services (OBS) is an internationally renowned organisation responsible for the television coverage and distribution of the signals of the Olympic and Paralympic Games to broadcasters around the world.
"OBS takes pride in ensuring that regardless of where the Games take place the professionals participating in the operation are provided with working conditions which are in line with the best practices of the industry at an international level and makes extraordinary efforts to help the development of broadcasting professionals at the host cities of the Games.
"The Broadcast of the Rio Olympic Games to the world involved the efforts of over 7,000 professionals from more than 70 different countries, including a large proportion of Brazilians who participated in the largest televised sport event in the world.
"With respect to the latest events, Olympic Broadcasting Services confirms that the lawsuit was brought to the company’s acknowledgement by a judicial order coinciding with the conclusion of the internationally acclaimed coverage that showcased to the world the best of Rio and Brazil.
"The company is already taking all legal measures in order to guarantee its defense in the lawsuit.
"Out of respect to the ongoing legal procedure, the company will not make any comments on any specifics while the case is under judicial review."
