A new picture of a suspect connected to the disappearance of Madeleine McCann will be released by British police, reports say.
British police have identified more than 40 people of interest in their investigation into the disappearance in May 2007 of Madeleine, aged 3 at the time, from an apartment in a Portuguese holiday resort.
But the inquiry team is known to be particularly interested in one individual, who is being viewed as a possible suspect, The Guardian reported.
Sky News reported that British detectives investigating Madeleine's disappearance are to issue the "e-fit" picture, but Scotland Yard would neither confirm nor deny the claim.
British police said on Wednesday (local time) that they wouldn't discuss the content of an upcoming appeal for information.
"We will be asking for help from the public in a number of countries, delivered through a series of public appeals.," police said.
"We will do nothing to jeopardise the effectiveness of these appeals and we have repeatedly stated that media speculation can be damaging to our efforts."
Madeleine disappeared from her family's holiday apartment in Praia da Luz in the Algarve on May 3, 2007 as her parents dined at a nearby restaurant with friends.
British detectives launched a fresh investigation in July this year - two years into a review of the case - and a new BBC Crimewatch appeal on the case is to be aired on Monday (local time).
The appeal will include a reconstruction of the "latest, most-detailed understanding" of the events around the time Madeleine went missing.
Scotland Yard has revealed a vast log of mobile phone traffic could be the key to finding out what happened to the girl.
Madeleine's parents have said they remained "optimistic" of finding their daughter and would not accept she was dead until they are presented with clear evidence.
The Metropolitan Police now has a team of six Portuguese detectives based in Faro who are carrying out inquiries on its behalf.
