Senior AAP leader Sanjay Singh said the "raid" on Sisodia's residence signalled the Modi government's "resolve" to not let the AAP regime in Delhi work.
The CBI has denied it has carried out a search or raid but only visited his house in connection with a case.
"So, did they (CBI) come for tea," Singh asked.
Displaying exasperation, Singh told a press conference that instead of the "daily harassment", the Centre should simply suspend the Delhi government.
The AAP government's tenure has been marked by intense acrimony with the BJP-led Central government.
"Today's raid signals the resolve of the Centre to not let the AAP government work. The BJP wants to obliterate the opposition. The intention is to take revenge through relentless harassment," Singh said.
The CBI, constituted as an autonomous body, had also raided the Delhi Secretariat in 2015, prompting Chief Minister Arvind Kejriwal to call Prime Minister Narendra Modi a "coward and a psycopath".
The government denies influencing CBI.
CBI officials said they "visited" the residence of Sisodia to seek clarification about a preliminary enquiry (PE) against him relating to alleged irregularities in a social media event by Kejriwal called 'Talk to AK'.
The CBI had registered the PE in January this year on the basis of a complaint filed by the Vigilance Department of the Delhi government.
It was alleged in the complaint that a consultant of a well-known PR company was hired by the Delhi government to promote the event and that a Rs 1.5-crore proposal was prepared for this purpose.
The PR firm, he added, was already working for the government and was "empanelled with it".
"So naturally, the government approached the consultancy. We may not have gone for a tender, but the point is this company did not charge any commission," Bharadwaj said.
The complaint said despite objections from the Principal Secretary, the government went ahead with the proposal. The consultant spent money on the campaign, thereby creating a liability for the government.
