This has been reported in dailymail.co.uk dated 22 January 2016.
Islamist militants have stepped up attacks on Egyptian soldiers and police since the army toppled Morsi in 2013 which came after mass protests against his rule and the neighborhood of Al-Haram has witnessed a number of attacks and gunfights since the overthrow.
The building housed many of Morsi's sympathizers and used to be a regular venue for clashes between his supporters and security forces in the aftermath of his ouster by then army chief and now President Abdel Fattah al-Sisi.
Moreover, the district also houses hotels that are frequented by tourists who come to visit Cairo, given its proximity to the pyramids.
The explosion came ahead of the anniversary of the 2011 revolution that ousted longtime autocrat Hosni Mubarak and security forces have interrogated residents and searched more than 5,000 homes in central Cairo as a 'precautionary measure' in order to prevent street protests on the anniversary.
