Rostock Hauptbahnhof has been reopened following a bomb threat that prompted a lockdown earlier today. The station was sealed off while police conducted a thorough search of the area, employing sniffer dogs as part of the investigation. The incident also caused delays for tram lines 4, 5, and 6. Authorities have yet to release further details about the threat. Police have confirmed the area is now secure, and services are expected to return to normal shortly.
