CAIRO: Unknown persons broke the window of opposition figure Hamdeen Sabbahi's car today. They examined documents and papers in the car but did not take anything with them. Sabahi's nephew was the first to see the broken car and the papers scattered inside it. The papers included demands from citizens who submitted their requests to Sabbahi, a presidential candidate. It is likely that the unknown people did not find what they were looking for and thus left the papers in the car after examining them all. The car was parked beside the headquarters of al-Karama Party, of which Sabbahi is the head. It is normal for Sabbahi to leave his car parked there.
