Hertha said on Tuesday that Mr Bernstein died unexpectedly at the age of 43.
An investigation into the cause of the death of Hertha Berlin President Kay Bernstein has been initiated, a police spokeswoman said.
According to the club’s spokeswoman, the investigation is a standard procedure carried out when the cause of death is unclear.
She said there are currently no indications of suicide or outside influence.
Hertha said on Tuesday that Mr Bernstein died unexpectedly at the age of 43.
Mr Bernstein, a passionate fan and former Hertha Ultra, had been the club’s president since June 2022.
The vice president, Fabian Drescher, will act as interim president of the second division club, but it’s not clear whether he will remain in the position until the elections in October.
It’s also unclear whether there could be early elections during the general assembly in the spring.
Hertha will host an open training session on Wednesday to give the fans the chance to express their condolences, while the pre-match news conference scheduled for Friday has been cancelled.
On Sunday, Hertha welcomed Fortuna Düsseldorf and thanked the cooperation between Sky and the broadcast rights holder for the second division.
The public broadcaster RTL and fans who were not in the stadium would be able to watch the game for free.
