Egypt's Zamalek Club Chairman Mortada Mansour withdrew on Saturday his legal complaint against 21 Ultras White Knights standing trial on charges of attempting to murder him last August.
Mansour, however, did not ask the court to drop charges against renowned Zamalek Ultras member Sayed Moshageb.
The request by the lawyer-turned-club-president to close the case against the 21 defendants is not binding for the judge.
Giza Criminal Court has ordered the release of the five defendants who had been apprehended in the case, and adjourned the trial to 25 July for further deliberation.
The rest of the defendants have been tried in absentia.
In August 2014, unidentified gunmen opened fire at Mansour as he was leaving Zamalek Club premises.
The 63-year-old Mansour escaped unharmed, but two workers at the club were injured.
Mansour — who was elected president of the Zamalek Club for the third time on 28 March 2014 — has been a controversial figure in Egyptian politics since the 1990s, as he accumulated a resume full of controversial lawsuits he filed against his crirics and firey public statements.
Mansour was one of several figures from the era of ousted president Hosni Mubarak accused of orchestrating the Battle of the Camel, when pro-Mubarak thugs attacked protesters in Tahrir Square riding camels and horses on 2 February, at the height of the 2011 revolution, killing 11 and injuring several hundreds.
He and 24 others were acquitted in 2012 on charges of inciting violence in the case.
