A man suspected of being a member of Islamic State has been arrested near the German city of Leipzig.
The 29-year-old man, who has been identified only as Ahmad AA, is also thought to be a former member of the extremist Syrian rebel group Jabhat al-Nusra, which is affiliated to al-Qaeda.
He was arrested during a raid on Thursday evening by officials from the Saxon police and Bavarian state criminal police, who also searched his apartment, according to German newspaper Bild.
According to the arrest warrant, Ahmad AA joined Jabhat al-Nusra during the early months of the Syrian civil war, and rose to become an Emir, or commander, in Raqqa - which has become the main bastion of Isis in Syria.
He reportedly participated in the conquest of the cities of Dibsi Afnan and Tabqa, before defecting to Isis in spring 2013.
The suspect is to be presented before the Federal Court of Justice today (May 5), when the arrest warrant will be presented.
