English: Early afternoon 2012-02-04 on Mansour Street, Egyptian CSF fire tear gas canisters into a large crowd of protesters gathered near the Ministry of Interior. The crowd flees northwards across Mohamed Mahmoud Street and towards Falaki Square. This area is situated about half a kilometre east of Tahrir Square in Downtown Cairo.

Photographer Alisdare Hickson writes, "There were many people very badly effected by the gas. I saw one man in convulsions. The next day, 5 February, I was arrested about 100 metres from this spot in an alleyway off Falaki Street. I spent the next 54 days in prison before being deported to the U.K.
