"Dhoni's security is foolproof," Kumar said, denying reports that the cricketer's security has been reduced following a review by a security committee.
"I tell you, there won't be any compromise on his security," the DGP added.
A newspaper today published that Dhoni's security cover has been reduced from Z to Y category.
A few years ago, Dhoni's security was tightened after his family received extortion threat through a letter. Later, the accused was arrested.
