"Unfortunately some people who downloaded the digital pre-order of Grand Theft Auto 5 through the PlayStation Store in Europe were able to access certain GTA5 assets leading to leaked information and media from the game appearing online.
"As you can imagine, we are deeply disappointed by leaks and spoilers being spread in advance of the game's launch.
"GTA5 represents years of hard work by many people across the world, and we all couldn't be more excited to finally share it with you properly this 17 September."
'Spoiling the ending'
The company warned that anyone posting plot details from the game ahead of its release would be temporarily banned from its community. However, this was too late for some fans who said they were disappointed to learn of details which previously had been securely under wraps.
One user commenting on the Sony blog said: "Thanks a lot Sony for basically spoiling the ending of GTA5 before the game was even released." In its statement, Sony said it had now removed the digital pre-order file from the European PlayStation store."
So basically encryption is still a problem at Sony
