The world of sport has been warned over its involvement with the Kinahan organised crime group, which has been hit with worldwide financial sanctions.
A well-known figure in boxing circles who has worked with world champion Tyson Fury and Josh Taylor is among those who have been sanctioned.
If you deal with individuals or businesses that have been sanctioned, you are involved in a criminal network, said Drew Harris, the Irish police commissioner.
There are no allegations of wrongdoing against any boxers who have worked with Kinahan.
Irish, American and British law enforcement launched coordinated action against the Irish Kinahan gang in the 1990s, which the US says is one of the world's largest crime groups.
The US is offering a $5 million reward for information on the three most senior members. Seven members and three businesses are targeted.
Harris said that they made it clear through this announcement who and what the Kinahan organised crime group is.
Specific individuals have been sanctioned. It is for businesses to make a decision about the integrity of their own business, the reputation of a sport, and also their fans, and whether or not they should carry on in any business dealings. That is not allowed in the US.
The assistant commissioner John O'Driscoll told reporters at a news conference in Dublin his influence was destroying or attempting to destroy a sport that is so important to inner city communities.
A number of boxing's leading fighters are represented by the MTK Global agency, including Fury. He says he cut ties with the company.
Last year, Tyson Fury thanked Kinahan for arranging a high-profile bout with Anthony Joshua, which later fell through, even though Kinahan says he is no longer associated with the agency.
A few weeks ago, Kinahan was photographed with Fury.
Kinahan was an adviser to Taylor, who is also represented by MTK Global.
Kinahan is a great adviser, who is doing great things for the sport of boxing.
Top Rank and Taylor have been contacted by the BBC.
Despite his links to the drug trade, boxing chiefs have defended his involvement with the sport.
The Irishman was offered his full backing by the World Boxing Council president after a meeting. The World Boxing Council has been contacted by the BBC.
Hoopoe Sports is a sports management company that is sanctioned by the US. A number of prominent boxers are listed on the website.
The boxing company, Probellum, denied any involvement with Kinahan.
Kinahan insisted that allegations of criminality are part of a campaign against him after a BBC investigation revealed his continued presence in the sport.
It is a matter for sport and leaders of sport to take a look at who they are doing business with and whether they are comfortable with that and take the right steps, according to the National Crime Agency deputy director of investigations Matthew Horne.
That is an appropriate matter for the sporting community to address.
The sporting bodies and broadcasters need to take great care and make sure that Kinahan doesn't have any ties to any organisation they do business with.
He said that if there is a relationship with Daniel Kinahan then he is sanctioned and that has implications for other organizations.
It will be a matter for sport and sport organizations to make those assessments based on what we have released today.
Sky Sports said it is aware of recent developments and the sanctions.
It said that they always scrutinize and act responsible in their boxing relationships.
