A MUM has claimed the Madeleine McCann suspect Christian B exposed himself to her daughter while trying to chat to her.
Paedophile Christian B, 43, was caught with his trousers down under a slide in San Bartolomeu de Messines, 40 miles from Praia da Luz, Portugal, where Madeleine disappeared when she was aged three.
The German national was arrested in 2017 after he committed a sex act in front of four youngsters.
Christian B was extradited to Germany and is currently behind bars for drug offences.
The new revelations came in a half-hour investigation aired by Portuguese TV broadcaster RTP.
The mum of the then eight-year-old said: “If he had snatched one of the children and put them in his van, we might never have seen them again.
“He could have gone anywhere. It’s still something that haunts me. I was left feeling very frightened. I think we were very lucky.”
Nelia Bras, mum of one of the youngsters Christian B allegedly pleasured himself in front of, added: “My daughter was eight at the time. He spoke to her in English and asked her, ‘What’s your name?’
“It’s very traumatic knowing that someone who’s been linked to so many cases and is perhaps a very dangerous man was so close to my little girl”.
It was revealed yesterday a British cop lived next door to Christian B.
The Portuguese home of the unidentified Scotland Yard detective was alongside the isolated villa in Foral where Christian B lived in 2007.
Madeleine had been on holiday with her parents Kate and Gerry McCann, and her twin siblings, Sean and Amelie, when she vanished without a trace on May, 3, 2007.
Her parents have always held out hope that she would one day be found alive.
However authorities in Germany have said they were now treating the case as a suspected murder and knew how the toddler had been killed.
A former pal of Christian B claimed last month the suspect fantasised about creating a Josef Fritzl-style dungeon at his home.
Christian B’s pal – who wanted to remain anonymous – led a TV crew to the house where the twice convicted paedophile was living around 2013.
He alleged that the now 43-year-old German had confided in him that he dreamed of turning the cellar of his rented home into a basement liar.
Christian B is said to have wanted to create a dungeon like the one Fritzl built with soundproof walls.
There is no evidence to suggest the suspect ever followed through on this idea.
German police revealed him as a new prime suspect in the 13-year-old case last month – and have insisted they believe he abducted and killed the three-year-old in 2007.
