German authorities have opened an investigation into Jumbo-Visma rider Michael Hessmann after the 22-year-old tested positive for a banned diuretic on June 14, 2023.

According to a report by Dutch television station NOS, the investigation included a search of Hessmann's home in the Freiburg region, where state police found no doping substances but seized data storage devices - most likely computers and/or cell phones.
