Saber Amin Farhat, the main defendant suspected in the arson attack on the town's church was arrested while in possession of wires and electrical circuits, a source in the Interior Ministry told state-run news agency MENA.
The source stressed that authorities intend to continue the operation in Kerdasa until it is fully cleared of so-called terrorist elements and dangerous criminals.
As part of its fourth day of operations in the city, security forces continued raiding homes of suspects and combing agricultural areas for criminals.
The number of suspects arrested now stands at 132, with individuals facing charges which include resisting arrest, attempted murder of army and police officers, and throwing hand grenades at troops during their invasion of Kerdasa.
Major General Mohamed al-Sharqawy, head of Giza's investigations department, said they have identified the suspects accused of killing Major General Nabil Fara, deputy head of Giza Security Directorate, who was killed during the security invasion of the city on Thursday.
Sharqawy said that it is unlikely that main suspects who incite violence, such as Abdul Salam al-Bashandy, may have escaped out of Giza, since army and police checkpoints have tightened the noose on suspects still at large.
In his opinion, suspects are likely to be hiding in areas near Kerdasa at relatives' houses.
The forces are carrying out raids around the clock to catch those on the run, especially Nahiya, Beni Magdol and Abu Rawash.
He also ruled out the escape of Assem Abdel Magued and Tareq al-Zomor, leading members of Jama'a al-Islamiya, outside Kerdasa and Nahiya.
He anticipated that the main suspects responsible for inciting violence will all be arrested soon.
