German Police detain for who planned to disrupt half marathon
One of the suspects is believed to have been planning a knife attack at the popular event, which drew a record 36,000 athletes this year.
Berlin police said they had detained six suspects aged between 18 and 21 after searches in three districts in the capital.
The Berlin half-marathon is the biggest in Germany, and thousands of people lined Berlin streets to watch the event.
The local daily Tagesspiegel reported that the main suspect had been under observation for two weeks around the clock. After a foreign intelligence service tipped off German authorities that he was planning to attack the half-marathon, police raided apartments and two vehicles in the Charlottenburg and Neukoelln districts of the city.
