German
police on Tuesday arrested a Syrian suspected of planning an Islamist attack, officials said, with public broadcaster ARD reporting that the man was at the top of the federal police's list of dangerous Islamist extremists.
The suspect exchanged
bomb building know-how through an extremist messenger group with links to the
Islamic State group, apparently preparing the construction of a bomb.
German police last Tuesday detained three people in the western city of Offenbach on suspicion of planning a bomb attack for the Islamic State militant group.
