MADELEINE McCann prime suspect Christian B has been moved to a new high-security prison dubbed Germany's Alcatraz.
The convicted paedophile, 44, who German investigators believe murdered Madeleine in 2007, is now locked up in solitary confinement at Oldenburg prison near Bremen.

The prison in north west Germany is covered in CCTV cameras - with doors and windows made from specially reinforced safety glass so jail guards can keep a close eye on the dangerous inmates, the Mirror reports.
The high-tech facility, which is surrounded by a 22ft wall, is deemed inescapable, apart from one incident where a prisoner managed to flee after making friends with a guard.
Speaking to The Mirror, Christian B’s lawyer, Friedrich Fuelscher, declined to comment on why he had been transferred.
But it comes after he fell and broke his ribs in a scuffle with guards at the grim Wolfenbüttel prison near Braunschweig.
Previously he was held in Kiel but was reportedly unhappy because he was bullied by other inmates for his alleged link to the McCann case.
Christian B, a prolific burglar, who also has previous convictions for sex crimes against young girls, was named as the prime suspect last year.
But he has denied any involvement in the alleged snatching of the child.

Police said he was regularly living in the Algarve between 1995 and 2007 and had jobs in the area, including in catering, but also committed burglaries in hotels and dealt drugs.
The suspect is currently serving seven years for the rape of an elderly woman in Praia da Luz in Portugal’s Algarve coast in 2005 who was attacked in her own home.
He was arrested 12 years after that attack.
Madeleine vanished from the same town in 2007 while on holiday with her parents Kate and Gerry and her siblings.
