The National Union of Journalists (NUJ) has been forced to apologise for mistakenly suggesting one its own members had been involved in "terrorist activity".
A document sent to the Home Office and published on the union's website said that photogrepher Marc Vallee was prevented from covering a protest at the Greek embassy in London in 2008 "for reasons of terrorist activity".
The error was in a submission about how the Terrorism Act 2000 has been misused against journalists.
A report of the original incident and the full apology to Vallee are on the NUJ's website.
Ironically - as Vallee points out on his blog - he is one of the founders of the I'm a Photographer Not a Terrorist campaign which defends the right to take pictures in public places.
