The Delhi government's revamped anti-graft helpline received 12,731 calls within 24 hours of being launched on Sunday.
The government said while it was analysing all the calls to segregate between frivolous and real calls, some complaints of corruption against officials of civic bodies and other departments have already been forwarded to its Anti-Corruption Branch.
"Several calls were related to complaints against the officials of Delhi Police, education department, transport department, Jal Board, Delhi Fire (Services)," an official statement said on Monday.
Efforts are being made to ensure that no call made on 1031 helpline number remains unanswered, it added.
Amid a boisterous crowd in Delhi's Talkatora Stadium, Chief Minister Arvind Kejriwal on Sunday relaunched the 1031 helpline -- started during the 49-day stint of the AAP government earlier -- to curb bribery in government offices.
He also pledged to make Delhi the first corruption-free city in the country.
The Aam Aadmi Party government claims the helpline -- a one of its kind -- will help to substantially reduce corruption in the capital.
