In addition, a known clan member was found guilty recently of breaking into the premises of a company in Bavaria that makes the devices, the newspaper said.
In response to a question from dpa, Dresden prosecutors' spokesman Juergen Schmidt said the investigating team was in contact with its Berlin colleagues with a view to finding parallels with the 2017 theft of a 100-kilogram gold coin - the Big Maple Leaf - from a Berlin museum.
After breaking a window at the Green Vault in the early hours of November 25, two unidentified suspects used an axe to knock three holes in display cases in the jewel room. The jewellery sets that were targeted contained around 100 pieces overall.
The Green Vault houses one of Europe's oldest and best-preserved collection of treasures. The coin stolen in Berlin is thought to have been melted down.
