The Attorney General today urged the media to show restraint in its reporting of the Suffolk murders and said he would review the coverage if necessary.
Lord Goldsmith issued guidance to newspaper and broadcast editors about the continuing investigation after contact with the Suffolk Constabulary.
The Government's top legal adviser said the force had "expressed concern" that recent reports were hindering its inquiries.
"The wide media and public interest in this police investigation is wholly understandable.
"However in view of the concerns that some coverage may impede the police investigations, the Attorney General asks all parties to exercise restraint in their reporting."
Lord Goldsmith said he would review the coverage "if and when appropriate".
The Contempt of Court Act 1981 is applicable from the moment of arrest.
He urged editors to avoid publication of anything which could prejudice a trial or potential prosecution.
This included speculation about suspects or material which "asserts or assumes, expressly or implicitly" a person's guilt, he added.
