Pictured: The teenage girlfriend Maddie McCann suspect used to beat up, who could help solve mystery

Police believe a former girlfriend of Christian Bruecker, whom it is claimed he ‘beat black and blue,’ could cold vital clues over the disappearance of Madeleine McCann. 

Nakscije Miftari was the teenage girlfriend of Christian Brueckner, the man widely believed to be responsible for the four-year-old’s disappearance in Portugal in 2007.

However a family friend says she has been laying low following revelations that her former boyfriend is suspected of multiple crimes.

The German authorities have issued an Interpol Red Notice for the immediate apprehension of Nakscije Miftari who they believe may hold vital information about the Madeleine McCann case.

Detectives in Britain and Germany want to quiz her about what she knows about Brueckner’s past, in particular his time in Portugal.

Brueckner seduced Nakscije after he set up home in a run-down part of Braunschweig, a crumbling industrial city in northern Germany, and ran a kiosk selling beer, soft drinks, snacks and sweets.

He later took Nakscije, who is German of Albanian descent, to Portugal in 2014 but she was deported back to Germany less than a year later following allegations of criminality.

However the couple split up and Nakscije reported Brueckner to the police over his violence.

‘Nakscije reported Brueckner to the police,’ a family friend told MailOnline. 

‘She was only a teenager when they got together, 17, I think. He was much older.

‘They lived in a flat together here in Braunschweig, around the corner from the kiosk he ran.

‘She is a very nice girl. But she was terrified of him. He is completely mad.

‘Brueckner took her to Portugal in the spring of 2014. But she was deported from Portugal in 2015.

‘Brueckner also came back to Germany a few months later. They continued to live together but they kept arguing and fighting.

‘They finally split up when he tried to kill her. He beat her black and blue.

‘Brueckner disappeared and Nakscije was given counselling.

‘After he left Braunschweig he tried to keep in contact with Nakscije. Brueckner would keep phoning her, telling her that he loved her and missed her.

Detectives hope for jail confession

Prison staff are keeping Christian Brueckner under surveillance in the hope he might confess or reveal details to a fellow prisoner.

Police lack a ‘knockout blow’ despite significant evidence linking him to Madeleine’s disappearance, a source told The Sunday Times.

And former British policeman Mark Williams-Thomas told The Sun that German investigators lacked ‘a body, hard evidence, and a confession. The best chance now is for someone known to Brueckner to break cover. With evidence lacking, my worry is police won’t reach a threshold to charge him’. Brueckner is in prison in Kiel, northern Germany, for a drugs offence.

‘But he was always out of his mind on drugs. He was always drinking and taking drugs.’

The family friend revealed that Nakscije started to lay low after Brueckner was named as the prime suspect in the Madeleine McCann case on German TV last week. 

Police want to speak to Nakscije after a British ex-girlfriend of Brueckner was quizzed by police. 

The unnamed woman, from Berkshire, is said to have lived in Praia da Luz where she dated German paedophile Christian Brueckner for around a year from 2004 – three years before Madeleine went missing.

She is not a suspect in the case, but according to reports, has agreed to cooperate with police and has twice spoken to detectives investigating her former partner.

The mother-of-two, who is still living in Portugal, was interviewed last year by police as part of the investigation into Brueckner, and, according to The Mirror, has spoken to them again in recent days after the 43-year-old was identified as a prime suspect in the Madeleine case.

Brueckner is currently serving a jail sentence in Germany for the rape of a 72-year-old woman in Portugal. 

But he is reportedly eligible for parole this weekend and one friend has since revealed to the Sun that the unnamed woman is terrified he will come after her.  

The friend said: ‘She’s really nervous, she knows B is in prison but fears he could be released one day and come after her.

‘It’s true they were together.’

Meanwhile, the Mirror say the woman’s British ex-husband, a businessman who also lives in Portugal, was also spoken to by Interpol last year in connection with Brueckner.

He told The Mirror: ‘We’ve decided not to talk.

‘The police have been in touch and we’ve spoken to them. We don’t want to be involved in this.’ 

Hans Christian Wolters, state prosecutor for Braunschweig, yesterday confirmed those in Germany ‘assume there are more victims’ who have not yet been identified.

He also revealed the suspect’s connection to Madeleine is so-far based on ‘circumstantial suspicion’ and Brueckner hasn’t yet been questioned by police, the Telegraph reported.

Authorities believe Brueckner may be involved in the disappearance of multiple children, and are determined to find enough evidence to link him to at least one case.

But German laws allow a suspect to access their case file as soon as they are identified, and prosecutors want to prevent Brueckner’s legal team from seeing the file until they are ready to charge him. 

Christian Brueckner ‘not involved in Maddie’s disappearance’ says Portuguese police official 

Christian Brueckner, who German police believe killed Madeleine McCann, was not involved in her disappearance, it was claimed by a senior Portuguese police official.

The statement was made to a respected Spanish newspaper by an unnamed Portuguese police chief.

The officer, described as a former Policia Judiciaria chief with in-depth knowledge of the Madeleine McCann probe who still works for the force, told ABC: ‘There’s no evidence Christian Brueckner is involved in her disappearance.

‘Strong enough reasons to be able to charge him were never found.

‘People talk about surprises in the Madeleine McCann case with the capture of this German man, but for me it’s no surprise.

‘This individual was already investigated around four years ago.’

Insisting the aim of German police revelations about the man, now identified as the prime Madeleine McCann suspect, was simply to put the case back into the public eye, ABC quoted the veteran PJ boss as saying: ‘At this stage of the investigation, I think they’ve done it because they think it’s needed to shake up the case and attract new witnesses.

‘They work very closely with Portugal and now they’ve wanted to turn this case around.

‘They’re not looking to solve it now, because that’s very difficult. What they’re looking to do is agitate the waters.’

It is the first time any high-ranking Portuguese police officer has been publicly quoted as saying he does not believe Brueckner is regarded as a genuine Madeleine McCann suspect, even though he appeared to hide behind the cloak of anonymity for the interview.
