Authorities in northern Germany have appealed to thousands of people to get another shot of Covid vaccine after a police investigation found that a Red Cross nurse may have injected them with a saline solution.

The nurse is suspected of injecting salt solution into people's arms instead of genuine doses at a vaccination centre in Friesland - a rural district near the North Sea coast - in the early spring.
