German police Tuesday arrested one of the country's most prominent Islamist preachers on charges of supporting a "terrorist group" fighting in Syria, AFP reports.
The man, German citizen Sven Lau, 35, made headlines last year by organizing a vigilante "Sharia Police" group that patrolled German streets seeking to enforce Islamic law.
Lau is accused of supporting and recruiting fighters for the Syria-based Jaish al-Muhajireen wal-Ansar (JMA), or Army of Emigrants and Supporters, which Germany lists as a terrorist organization.
