Amnesty International have apologised to Iggy Pop for using a beaten and bloodied image of the rocker on a poster without his permission.
The poster also attributed an incorrect quote to Pop that claimed he had said: "Justin Bieber is the future of rock and roll".
In an apology on their website, Amnesty wrote that the image and quote were supposed to be ironic in an attempt to highlight their campaign against torture.
"To generate awareness about our campaign against torture, Amnesty International Belgium French speaking section used an image of Iggy Pop without his authorisation.

"Even though we acted in good faith, we would like to apologise to Iggy Pop for having done so ... We would therefore also like to make it clear that the statement attributed to Iggy Pop that he believes Justin Bieber is the future of rock and roll does not represent Iggy Pop's personal opinion but was part of the creative process for this campaign and was intended to be ironic."
The poster made headlines when it was released, mainly because of the quote about Bieber.
Amnesty also apologised for using an image of the Dalai Lama in a similar way.
Pop hasn't commented on the photos, but he did issue one tweet about it:
