It's 12 years since the 3-year-old went missing in Portugal.
(Image source: irishmirror.ie)The new suspect in the Madeleine McCann case is a German man already being investigated over alleged child sex offences.
He's thought to have been living on the Algarve coast when Madeleine vanished 12 years ago.
The man, who wasn't a suspect at the time, is one of two people being looked at by detectives in Portugal and the UK.
In the UK, Scotland Yard confirmed it's asked for more funding from the Home Office to continue looking into the disappearance of Madeleine McCann in Portugal.
The Metropolitan Police investigation has cost more than £11 million so far - but officers want to follow up leads.
Reports in Portugal suggest extra police have been drafted in to investigate new leads over Madeleine McCann's disappearance.
Sky's crime correspondent, Martin Brunt, is in Praia da Luz, where Madeleine went missing - and is following the latest report there:
"It talks about somebody who was known to the authorities before Madeleine disappeared 12 years ago - and had even been over child sex attacks, but investigations that have come to nothing."
Anthony Summers is the co-author of the book, Looking for Madeleine.
"If you took a map and took the little towns around Praia Da Luz...there were known paedophiles or suspected paedophiles, who had been working or operating, or at some point arrested."
Madeleine was nearly four when she disappeared from her parents' apartment in Praia da Luz in 2007.
