BERLIN, Nov 30 (Reuters) - German sporting goods retailer SportScheck, part of the debt-addled Austrian property empire Signa, will file for insolvency with a court in Munich on Thursday, the DPA news agency and other German media reported.

The court was not immediately available for comment and SportScheck was not reachable.

Signa declared insolvency on Wednesday after last-ditch attempts to secure fresh funding failed, making it the biggest casualty so far of a property crash in Europe driven by a sharp rise in interest rates and building costs.

The multi-billion-euro group, whose reach spans from Germany's best-known department store, Berlin's KaDeWe, to the country's top high-street chain Galeria and a skyscraper project, is set to send ripples across the continent's embattled property sector.
