Noting that 1,500 violators have been caught since the launch of drive last November, Deputy Chief Minister Manish Sisodia termed the move a "success".
The decision to issue WhatsApp number was taken at a review meeting, chaired by Sisodia, where senior officers of Excise Department briefed him about the action taken during the ongoing drive.
Sisodia, who also holds the excise portfolio, had launched the drive on November 7 last year, contending that consumption of alcohol in the open, particularly near liquor vends and in vehicles, was not merely a safety hazard but a major problem for women security.
In another tweet, he said, "We want to rope in people in the drive so that they could give inputs (about violators) ... For which Delhi government will soon issue a WhatsApp number where people can complain against people consuming liquor in public area."
According to the new law in Delhi, drinking in public and creating nuisance will attract a fine of Rs 5,000 and Rs 10,000, respectively, besides imprisonment of six months.
