The Aam Aadmi Party (AAP) will carry out a nationwide protest today against Deputy Chief Minister Manish Sisodia's arrest in the Delhi liquor scam case. Sisodia was arrested after nearly eight hours of questioning on various aspects of the excise policy for 2021-22 in connection with alleged corruption in the now-scrapped policy relating to the sale of alcohol. The national capital has been put on alert in view of the protests and elaborate security arrangements have been made by the Delhi Police to maintain law and order situation. Manish Sisodia will be presented before Avenue court today and the CBI is expected to get the custody of the minister.
