BERLIN (REUTERS) - Police said they detained a passenger who took a bus driver hostage on a southern German motorway on Tuesday (Sept 21).

"A weapon has not been found so far. The bus is still being searched," police added in a tweet.

They said passengers had earlier been able to leave the bus.

Police closed a section of the A9 motorway south of Nuremberg to deal with the incident.

"The motorway closure will be lifted shortly," they tweeted.
