The arrests were made on Tuesday morning as members of the Home Office Immigration Enforcement team carried out a raid on the group's suspected ringleaders. The BBC's Politics Investigations Correspondent, Billy Kenber, accompanied the officers during the operation.
The action comes after a BBC investigation earlier this year uncovered that law firms and advisers were helping migrants pose as gay in an effort to secure asylum. The extent of the network and the number of fake claims involved have not been officially confirmed, but authorities suspect it to be behind dozens of fraudulent applications.
The Home Office has not yet released further details about the individuals arrested or the specific law firms implicated.
