According to police, three of the accused work for Prime Focus Technologies, a Mumbai-based company that processes the series for Indian streaming website Hotstar.
Earlier, an upcoming episode of the seventh season of popular fantasy drama TV series "GoT" was accidentally broadcast in Spain on Wednesday, four days before its original scheduled telecast.
In a bid to contain further leaks from a group of hackers, HBO reportedly offered to pay $250,000 to the hackers who stole almost 1.5TB data, including scripts of "Game of Thrones" (GoT) and other employee information, from the TV network.
The hour was enough time for the episode to be ripped and shared online through torrent sites.
Another episode of "Game of Thrones" was released on Tuesday, the second confirmed leak to hit season seven.
That hack included the theft of proprietary information, such as programming.
A spokesperson for HBO told "CBS This Morning" the hacks are an effort, "to generate media attention".
In the latest attack, the company's Twitter and Facebook accounts appear to have been breached by a group called OurMine, which, in recent years, has taken over media accounts of Netflix, Marvel and Google.
HBO did not immediately respond to the BBC's request for comment.
