The 29-year-old driver who killed a teacher and injured 14 students by ploughing into them in central Berlin on Wednesday morning may be mentally unwell, German officials have said.
After hitting pedestrians and then crashing into a shop near Kaiser Wilhelm Memorial Church on the Breitscheidplatz, the German-Armenian man, who has been named by local media as Gor H, was stopped by bystanders and was later detained by police.
