BBC News/ Twitter photos

Your reporting of this evening's riot in Tottenham included photographs which you said, were "from Twittter".

You may have found them via that website but they would have been hosted elsewhere and taken by other photographers, whom you did not name and whose copyright you may have breached.

You have done this with other recent news stories such as the Oslo attacks.

This is not acceptable.

In future, please give proper credit to photographers.
