The two departments which have the maximum interface with the public, are also the most corrupt, according to the number of corruption cases filed by Delhi's Anti Corruption Branch (ACB) in the last three years.
Delhi Police tops the list of government departments against whom the ACB has filed corruption cases, followed by the Municipal Corporation of Delhi (MCD).
As many as 59 cases were filed against Delhi Police personnel followed by 27 against MCD employees.
In all, as many as 300 Delhi government officials have been charged with involvement in corrupt activities between 2007 and 2010, the ACB said in reply to a Right to Information query by Ashwini Shrivastava.
While officer at the level of inspector is the senior-most police officer charged with corruption, the other officers, including those from the MCD include commissioners, executive engineers, junior engineers, and senior clerks among others.
According to the ACB, 57 cases were registered against 80 employees in 2007, 45 each in 2008 and 2009 against 122 and 64 officers respectively.
Out of the 22 cases registered till May this year, ten were against Delhi Police officials, three against MCD employees and six against employees of other departments of the Delhi Government.
Asked to comment on alleged instances of corruption detected by the ACB, the Delhi Police's Joint Commissioner (Vigilance) N Dilip Kumar said "We regularly organise vigilance checks in the department and act strictly on any complaints regarding involvement of any officials in corrupt practices.
"Recently, we had carried out sting operations to nail corrupt police officials," he added.
Asked about corruption in the MCD, its spokesman Deep Mathur remarked: "We have introduced e-governance in our departments to discourage corruption."
