Tahrir Square protest continues over police trial

4 June 2012 Last updated at 05:09 BST

Demonstrations have continued in Egypt's Tahrir Square over six former police chiefs, who have escaped punishment because of a "lack of evidence".

Egypt's state prosecutor has lodged an appeal against the acquittal of the men, who worked for the former President Hosni Mubarak.

Prosecutors are also appealing Mr Mubarak's 30 year prison sentence for his role in the deaths of 900 people during the revolution in 2011. Many activists were disappointed that the court did not sentence him to death.
