Protesters on Monday reopened Tahrir's Mugamaa - Cairo's largest bureaucratic office - after calls for civil disobedience.
Calling for civil disobedience, protesters forcibly prevented government employees from entering the premises on Sunday, leading to verbal confrontations.
A number of citizens had attempted to persuade protesters to back off but failed.
Protesters who are holding a sit-in in Tahrir Square had blocked the entrance to the building at the beginning of this month, listing down a number of demands.
These demands included justice for victims of recent clashes between the state and protesters, sacking the interior minister and attorney general, a new unbiased government to replace that of Prime Minster Hisham Kandil's and an assembly to discuss controversial articles in the new constitution.
