Genena's daughter Nada told Reuters that 30 security personnel have taken her father from his New Cairo home, saying she does not know his whereabouts.
The Egyptian army has said it will launch an investigation into Sami Anan, the former Egyptian chief-of-staff and Hisham Genena, the country's former top auditor, who had served as Anan's presidential campaign manager prior to its suspension. This was also confirmed by Genena's lawyer Taha Ali. Egypt holds the election at the end of March. However, the defendants claimed a fight broke out after their cars crashed.
Military Spokesperson Tamer EL-Refai said on Monday that the Egyptian Army will investigate statements previously given by the former top auditor stating that former candidate Sami Anan acquires documents which expose the Egyptian State's violations.
Over a dozen global and regional rights groups are saying that next month's presidential election in Egypt does not meet the "minimum requirements" for a fair and free vote and called on Cairo's allies to denounce the "farcical" election.
Geneina said that Anan told him that there are many facts hidden from public opinion, in terms of what happened both before and after January 25, which greatly changed the image of many people in power.
The ex-general was considered most serious challenger to President Fattah al-Sisi in next month presidential polls.
Genena was sacked from his job as auditor in 2016 after making public complaints about corruption.
Geneina was attacked and severely wounded two weeks ago while on his way to lodge an appeal against an electoral commission's decision to disqualify Anan from running in the presidential vote, scheduled for 26-28 March. He is still an officer called for duty under the decree, which was passed in November 2011, attributing military status to all members of the Supreme Council of the Armed Forces at the time, until their death. He was retired by democratically elected president Mohamed Morsi in a move that was viewed as way to loosen the military's grip on the country.
