Explosive experts sought to dismantle two suspected explosive devices placed in front of The Children's Garden in Cairo’s Nasr City on Easter Monday.
Police personnel used water cannons to defuse the bombs before they turned out to be a hoax, reported Al-Ahram’s Arabic news website.
Both devices were wired but didn’t contain any explosive materials.
Bomb attacks of different sizes have dramatically increased across Egypt since the ouster of Islamist president Mohamed Morsi in July 2013.
Public gardens are usually crowded on bank holidays.
