The station's supervising judge intervened on her behalf and told the officer that he needs her help, especially when counting the votes. The judge asked the officer to return to his post at the school gate where he waited for an opportunity to arrest Omran.
She is still being detained at the headquarters for the Cairo police department in Bab El-Khalq.

Hila El-Attar explains that she is voting ‘Yes’ “because what we wanted is done, those we wanted to leave have gone, and our demands are met.”
Layla Zarif, a 60 year old postal employee, differs. “I’m saying ‘No’ because now we don’t feel safe or secure.”
Each polling station has a popular committee, made up of three members and headed by a judge, to ensure the day passes without incident.

10:55 Our correspondent in downtown Cairo reports on her experience of voting for the first time: "We entered four by four (two females and two males). I got in they took my ID, copied the number. I asked how would you know if I voted twice and was told "if you did you will be jailed, all the documents will be compiled". Then I found the judge of the station over my head to answer my questions. The judge told me "we would know by the ink on your finger which won't wash off before tomorrow". He was nervous and said: "go behind the curtain and do what you want".
"In front of a polling station a guy asked "what are they doing?" I told him they are voting and he said: "I thought there are giving things away." He won't vote. A policeman told me "there are no monitors here. Whoever comes with a delegation from an NGO is not entitled to monitor. So the judge ask them to leave. Monitors should get approval from electoral committee.""

Meanwhile some women tell our correspondent that they didn't make a mark on their paper as they did not know what they were supposed to do. "They just learned that they lost their vote."
10:15 Arab League Secretary General Amr Moussa votes in Qasr El-Eini.

09:40 In Shubra "the split is very clear with Christians on one side voting 'No' and Muslims on the other," Ahram Online's correspondent.

08:40 With polling stations opening at 8am, long queues are already forming. In Sheikh Zayed, 6 October, thousands of voters of different ages and backgrounds wait patiently.
