The Tehran prosecutor says an internationally acclaimed Iranian filmmaker has been detained as he hosted guests at his home.

The state IRNA news agency says Jafar Panahi was taken into custody late Monday.

The Tuesday report quotes Prosecutor Abbas Jafari Dowlatabadi as saying the detention was not political. He said another person was arrested with Mr. Panahi.

The prosecutor did not elaborate but said the case is under investigation.

Mr. Panahi backed the opposition after the disputed June presidential election. He was briefly detained last summer when he visited the gravesides of the victims of Tehran’s post—election unrest and later banned from travelling abroad.

Mr. Panahi, who is 49, has won awards at the Chicago, Cannes and Berlin film festivals.
