Roger Baker, who led a review into police corruption for Her Majesty's Inspectorate of Constabulary, said: "Social networking is seen as a risk by all forces and authorities, but there are limited or inconsistent policies around what is acceptable, what you should do, what you shouldn't do.
"We found a significant blurring between people's professional lives on social networking sites and their private lives which may be in the public domain and private lives which probably should remain extremely private."
