The Metropolitan Police say they have identified 38 persons of interest in a review of the evidence in the case, the London Daily Star reported. They will be interviewed by Portuguese police.
Madeleine was 4 in 2007 when she vanished from her family's holiday apartment in a beach resort in the Algarve. Her parents, Kate and Gerry McCann, both doctors in Leicestershire, were eating dinner with friends at a nearby restaurant where they could see the window of the apartment from their table.
At one point, Portuguese investigators suggested Madeleine might have been a victim of child abuse. The McCanns have filed a libel suit against Goncalo Amaral, the Portuguese detective who once headed the investigation, and are seeking 1 million pounds ($1.6 million) in damages.
A court hearing on the libel case is scheduled for September, the Star said.
