Two and a half years after the spectacular theft of jewels from the Green Vault in Dresden, a seventh suspect has been arrested.

As announced by the public prosecutor and the police on Tuesday in Dresden, the 22-year-old was arrested on the sidelines of the main hearing against the six accused who were already before the Dresden Regional Court because of the crime.

The man was urgently suspected of having provided the other suspects "with knowledge of the entire crime plan, comprehensive assistance in planning and implementing the project," it said.

Investigators also examined the man's car and apartment in Berlin-Kreuzberg on Tuesday.

They were supported by officials from the Berlin police.
