Another episode from series seven of Game Of Thrones has leaked online

Game Of Thrones has suffered another leak but this time its makers can't blame hackers for the problem.

HBO Spain accidentally showed episode six of the current season of the show, which has now been shared on illegal streaming sites.

It was reportedly made available online for an hour to Spanish subscribers of HBO's online service.

But that was long enough for the episode to be ripped, uploaded and shared online.

HBO is said to be working to remove links to the leaked episode, so don't go hunting for it.

Series seven of Game Of Thrones has been the leakiest yet, with hackers having previously put the fourth episode online.

Four people were arrested in India this week in connection with the leak.

Earlier this month, HBO's internal servers were hacked, with scripts and the personal details of Game Of Thrones actors shared online.

Spoilers for the sixth episode, by those who have seen the leak, have appeared on social media annoying other viewers of the show.

This Twitter user summed up her feelings with a GIF of Sansa Stark.

She wishes she hadn't looked online for spoilers.

If everything had gone to plan, Game Of Thrones fans would only have seen one minute of footage from the next episode.

Here's a 60 second trailer for the leaked episode.

But the stars of the show aren't worried about people seeing the newly-leaked episode, saying the previous leak didn't affect ratings.

"There were always going to be people who want to find out more but I think it's just a tiny, tiny fraction of the people who love the show," says Nikolaj Coster-Waldau, who plays one-handed, incest-loving army captain Jaime Lannister.

"Why would you want to spoil it for yourself? Episode four was leaked. That didn't hurt the ratings at all."

You can legally watch episode six of series seven of Game Of Thrones on 21 August, when it airs in the UK.
