The Government has warned the media over its reporting on the Metropolitan Police's investigation into murder and child abuse by establishment figures.
Editors and publishers have been told that the Attorney General's Office is "monitoring" their coverage of Operation Midland.
And the Solicitor General, Robert Buckland QC MP, has issued a statement to "remind editors, publishers and social media users" that those who allege sexual offences cannot be identified.
The press has also been warned off giving the impression of "pre-judging the outcome of the investigation".
The statement in full said: "The Metropolitan Police Service (MPS) is currently investigating allegations made by a complainant that he was sexually abused by a number of men including various high profile figures.
"The Solicitor General, Robert Buckland QC MP, would like to remind editors, publishers and social media users that where an allegation of a sexual offence has been made, no matter relating to the complainant shall be included in a publication if it is likely to lead to members of the public identifying him. Publishing such material is a criminal offence and could be subject to prosecution.
"In addition, while the Solicitor General recognises the legitimate public interest in the press commenting on cases of this nature, he wishes to draw attention to the risk of publishing material that gives the impression of pre-judging the outcome of the investigation and any criminal proceedings that may follow, or which might prejudice any such proceedings.
"The Attorney General’s Office will be monitoring the ongoing coverage of Operation Midland and editors and publishers should take legal advice to ensure they are in a position to comply with their legal obligations."
