Sisodia told the media that the BJP should apologise to the people of Delhi for calling them "freeloader".
He said it is the duty of every government to serve the people.
"We are here to serve the citizens of Delhi. By calling the public freeloader, BJP is insulting the parents who send their children to a government school. We won't tolerate this humiliation of our people," said Sisodia, who is the Education Minister.
Sisodia said the remarks from a BJP leader was an "insult to people because taking free services from the governmnet does not mean people are freeloaders".
"The BJP leaders have said that they are against the free electricity, water and travel for women in Delhi. By saying that people of Delhi are freeloader, they have insulted the public.
"The people of Delhi are not for sale here but are the owners of the city. BJP President Amit Shah should apologise to the people of Delhi," Sisodia told media.
He said the governments are here to serve the people.
"People are paying taxes and the money from that are used for development. Getting free service from the government does not mean people are on sale. The BJP have been against our free schemes," Sisodia said.
He accused that the BJP wants to give benefits only to the rich. "People are paying taxes and AAP is giving them free services. This is their right."
Sisodia, who is also the Finance Minister, said people anyway don't have money as the economy is going down. "Why do you want to put more pressure on them?"
He said the BJP is against free electricity, free water and free travel for women. "This can be their agenda as a party but they cannot insult the people of Delhi who are the beneficiaries of this pro-people policies."
This comes after a verbal spat between AAP and BJP's Delhi unit chief Manoj Tiwari who has promised five times more benefit to the voters than AAP has given in the past five years.
Sisodia asked Tiwari to show the report card for those states ruled by the saffron party, after his "five-time" promise came.
