Dortmund (Germany): German investigators yesterday detained a suspect over a blast that hit Borussia Dortmund's team bus, prosecutors said, confirming a possible "terrorist link".

The blast had a radius of more than 100 metres (yards), federal prosecutors said. Federal prosecutor's office spokeswoman Frauke Koehler said the probe was examining a "terrorist link", after three identical letters were found at the scene. "An Islamist background appears to be possible," she said
