The leak originated from Indian distributor Star India, a subsidiary of 21st Century Fox, which has since confirmed the authenticity of the pirated copy.
All of those arrested either work or worked from Prime Focus Technologies, a data-management vendor that does business with Star India.
The episode in question, which was the fourth installment of the current season and was titled “The Spoils of War,” first appeared on Reddit ahead of its airing in August.
There, it reportedly was shared via a Google Drive link that has since been taken down.
