Prosecutors in Serbia say there is no evidence to suggest that Novak Djokovic submitted falsified Covid test certificates to Australian authorities.
A BBC report last week cast doubt over the tests, suggesting the serial numbers were out of sequence with others from a similar time.
The tests were provided to exempt him from rules barring unvaccinated people.
The Belgrade Public Prosecutor’s office has now said that the Health Ministry confirmed the documents were authentic.
The office says it inspected the “electronic database” which contains details of tests and results and it shows that Djokovic’s initial positive test and his later negative result were both valid.
