Take-Two has issued an official statement blaming a Sony Europe employee for leaking Manhunt 2 code onto the Internet.
Until now, the person responsible for the September download had been named only as someone who had access to the game.
"Take-Two Interactive has confirmed that a former employee of Sony Computer Entertainment Europe (SCEE) has acknowledged his responsibility for the unauthorized online distribution of an unrated play-test version of Manhunt 2 submitted for the European PAL PlayStation 2 computer entertainment system," the publisher told GamePolitics.
Manhunt 2 was denied the right to be sold in the UK for the second time at the beginning of October, after the BBFC claimed the changes made to the game had not gone far enough to grant it a green light.
However, its decision has been brought back to the attention of the media after David Cronenberg's violent latest, Eastern Promises, was deemed okay for UK audiences despite featuring scenes gruesome enough to make people turn away from the screen.
"These days we are not here to cut; we are here to provide information and let people then make up their minds... People also have expectations of what a Cronenberg film is," the BBFC told The Times.
Manhunt 2 has been given the go-ahead in the US under a Mature 17+ rating, and in Holland where you will have to be over 16 to buy it.
