Egypt's Supreme State Security Prosecution services has released a businessman arrested on suspicion of orchestrating aggression against pro-democracy protesters on 2 February.
Thugs detained by military police following the assaults said that Mohamed Ibrahim Kamel, a businessman, was among those who financed and planned an attack on Tahrir Square carried out using camels and horses.
A video report by Sky News had claimed that Kamel, a close friend to former president Hosni Mubarak and his son, Gamal Mubarak, was the first to urge a counter-revolution.
But Kamel told investigators he had no links to the incident and the accusations were malicious. Prosecutors decided to release Kamel pending investigations, citing a lack of evidence.
Kamel told investigators he had only called for pro-Mubarak protests at Giza's Mustafa Mahmoud Square, and did not intend to cause any friction with Tahrir protesters.
