Ten people have been arrested for allegedly attacking two Muslims from the An'Nur Winterthur mosque for talking to journalists.
The group are alleged to have physically attacked and detained the two Muslims inside the mosque and threatened their families back in November 2016 after they gave information to journalists about an imam who called for non-practising Muslims to be killed.
The people aged between 17 and 53 were arrested on Tuesday in Winterthur and the surrounding area. Around a dozen houses were searched.
Criminal proceedings have been opened by the Zurich attorney general against the group for assault, confinement, threats, coercion and bodily harm.
