COPENHAGEN (REUTERS) - Danish police briefly shut bridges and ferry links to Sweden and Germany on Friday (Sept 28) as they widened their hunt for three people and a black Volvo in connection with a serious crime - a kidnapping according to Sweden's Aftonbladet newspaper - to include the whole country.
Denmark's armed forces said they took part in the operation, without giving details.
Danish police said they were still looking for a Swedish-registered rental car, and Swedish police said the car was rented at Malmö airport in August but hadn't been returned.
"The vehicle probably contains three persons linked to a serious crime," Danish police said in a statement.
"Copenhagen Police are searching for a black Swedish-registered Volvo V90 with registration number ZBP 546."
Aftonbladet, quoting unnamed sources, said the operation was linked to a kidnapping in Denmark.
Police would not confirm the report.
Earlier on Friday, police briefly shut the Oresund bridge and tunnel, a near 16km road and rail link with Sweden that featured in the TV crime drama The Bridge.
Other bridges, ferry services and Copenhagen's main railway station were also temporarily shut.
