Berlin authorities are the target of ridicule and disbelief after nine prisoners escaped or absconded from one prison in the space of five days.
Six remain on the run from Plötzensee jail after four separate incidents.
Last Thursday, four inmates used an angle grinder and hammer from the prison workshop to break through a ventilation shaft. They then crept under the perimeter fence.
Despite CCTV capturing the escape, it was 41 minutes before it was noticed.
