The Delhi police spokesperson has dubbed the sting operation as "totally bogus and incorrect".
"This sting operation, which is being shown, is totally bogus and incorrect. There is no lockdown in Jawaharlal Nehru stadium. When there will be a lockdown there, I can assure you, no one will be able to make an unauthorised entry. No one can enter during the games or the lockdown period. This is a deliberately planted story.
"Can't say anything else. This is a completely bogus and incorrect story. This is just being done to spread misinformation. Checkings are done only after the lockdowns," said Rajan Bhagat.
The footage of sting operation aired by Australia's Channel 7 shows its reporter carrying bag full of explosives past the security.
The channel's camera crew also claims to have filmed the sale of explosive material like ammonium nitrate and remote detonation kit. The salesman was reportedly in a car parked in the north of Delhi.
The Australian media report also claimed that the bag loaded with explosives had been taken past police security at the Jawaharlal Nehru stadium several times without being stopped for inspection.
"The reporter is trying to create false impression of security breach by walking from barricades placed on the main road only to divert vehicles," the spokesman said.
"That place is far off from the main entry gate of Jawaharlal Nehru Stadium from where the actual manual checking of pedestrians is done at this state and the reporter had not reached up to the checking point.
"Such a sting operation seems to be motivated and deliberately planted in which the reporter does not even know that ammonium nitrate is a fertiliser and a non-prohibited item for sale in India," the Delhi police spokesperson added.
