Media reports last week suggested Bradbury had benefited from Virgin Atlantic air miles and free flights to which she was not entitled.
She contacted entertainment PR specialist Taylor Herring after reading the allegations in the Daily Mirror.
Taylor Herring managing partner James Herring said: ‘We are monitoring the accuracy of media reporting and liaising with Virgin Atlantic, the BBC and the police at the highest level.’
Herring added: ‘We are being vigilant on her behalf to make sure there’s no trial by media. We’re 100 per cent certain her name will be cleared, but as her name is in the frame in a high profile investigation, it has made it difficult for her to carry on with her Watchdog duties.
‘This is very distressing for Julia. She’s been helping consumers who are unwittingly brought into difficult situations for years, but now she finds herself on the receiving end.’
Bradbury denies any wrongdoing and believes she has been a victim of cyber crime. She has voluntarily stepped down from the BBC’s consumer rights programme, which exposes scams, until the police investigation is completed.
Bradbury has worked with agency managing partner Cath Taylor several years ago.
