Addressing a rally in Amritsar, Mr Kejriwal said Mr Majithia had "played with the youth of Punjab by unleashing narco-terrorism in the state", and promised to put him behind bars.
Mr Majithia, who was probed by the ED in connection with the alleged Rs 6,000 crore money laundering drugs racket case, has often been at the receiving end of Mr Kejriwal's ire during the AAP convenor's election rallies in Punjab.
The state finance minister has denied the charges against him.
Mr Kejriwal also alleged that Punjab's ruling Badal family and PCC chief Amarinder Singh have "plundered" the state during the last 15 years and have left it in deep financial crisis.
He claimed they had promoted their family businesses by ignoring the interests of the public.
Accusing the Badal government of patronising drug mafia and criminals, Mr Kejriwal promised to work for the prosperity of Punjab if AAP comes to power in the poll-bound state in 2017.
He said political will is necessary for the welfare of public.
Citing the example of Delhi, he said that despite "numerous obstacles" thrown up by the Modi government, his government has provided state-of-the-art health facilities for people.
Changes have been ushered in the education sector as well with the infrastructure of government schools now matching up to reputed private schools, he claimed.
Speaking on the occasion, Punjab Affairs co-incharge Jarnail Singh said that the liquor shops and drug trade have increased manifold during the Badal regime while the schools have been shut down.
People are facing a lot of inconvenience and harassment in hospitals as the government hospitals are devoid of proper infrastructure, Singh said. He promised to reduce VAT and electricity bills if AAP forms the government in 2017.
