Former News of the World journalist Bethany Usher this week revealed she was wrongly arrested because a source failed to remember giving her access to a voicemail message.

Usher, who is now a lecturer on the undergraduate journalistm course at Teesside University, was cleared just eight days after being arrested in 2011 when she reminded the source that she had recorded evidence showing he had sold her the story.

She said she was arrested on the basis of one email provided by News International which referred to her transcribing a voicemail – but that this was taken out of context.
