The prime suspect within the disappearance of Madeleine McCann is reportedly not under 24.7 police surveillance.
There are fears Christian Brueckner could disappear nine months after he was released from prison last September.
The paedophile had been followed non-stop by officers since his freedom but a court ruled the police remark was not required.
Brueckner will still wear an electronic ankle tagto monitor his location, but prosecutors say the tech has malfunctioned prior to now.
Sources claim the tag will fail to work if he leaves Germany, warning he could soon vanish out of sight.

A source told The Sun: ‘The fear has at all times been that as soon as Brueckner got the chance he would disappear.
‘He may need been let loose of jail but he still hasn’t had that because he has been monitored by police all day daily.
‘Once that surveillance stops who knows what is going to occur.
‘He has a history of leaving the country when he faces suspicion so there’s a really real danger he’ll disappear before the McCann case can ever get to court.’
German cops within the Schleswig-Holstein state are understood to have appealed the choice to not renew the surveillance order.
Brueckner will remain under police remark until the court has made a final decision.
Madeleine was three when she vanished from the Portuguese resort of Praia da Luz on the Algarve while on a break along with her siblings and oldsters.
Prime suspect and convicted rapist Brueckner was released after serving a jail sentence in his native Germany last September.
He had been serving a seven-year sentence for an unrelated sex crime. Along with his conviction for the rape of the lady within the Algarve, he also has convictions for child abuse and drug trafficking.
State prosecutors in Germany have said there’s circumstantial evidence suggesting Brueckner was involved in Maddie’s disappearance, including three witnesses who said he had confessed to them.
He lived within the Algarve between 1995 and 2007, with a period spent working as a pool maintenance assistant on the Praia da Luz resort, where the McCanns were staying when their daughter vanished.
But extensive searches for more direct evidence have ended without success.
He has denied any involvement in her disappearance and has never been charged with any crimes in reference to Madeleine.
In March, it was announced that more funding had been granted to proceed to research the disappearance.
