The protesters, who were trying to reach the Assembly premises, were detained by the police, but later released.
The party's New Delhi MP Meenakshi Lekhi, MLA O P Sharma and many other partymen, including leaders of the Delhi BJP, participated in the protest.
"Corruption in government work is rampant. Every department has its own stories of corruption," the Delhi BJP's general secretary Ravinder Gupta said and demanded that the chief minister issues a statement on allegations of graft during his rule.
"This is being done to defame the civic bodies ruled by the BJP," he said.
The two-day special session of the Assembly called by the AAP government will discuss various issues, including quota for city students in DU colleges, report of a House committee on desilting of drains and weightage for local domicile candidates in teacher recruitment.
