Two men were detained at Indira Gandhi International Airport for carrying live cartridges on Tuesday morning. One of them was identified was Shiv Vardhan Singh, who is a nephew of an Uttar Pradesh minister.

Singh was to board an Air India flight for Mumbai when officials at the X-ray counter stopped him after they found a strip of 10 bullets of .32 bore in his hand baggage, said an officer.

"He said the bullets perhaps belonged to the minister's son, who has a licensed revolver.

We are verifying his claims," an officer said.

During baggage screening, a live cartridge was found inside his bag. He was detained by the security personnel at the airport and subsequently handed over to the police.

Another man who was detained was identified as Darshan Singh, who was to take flight to take to Malaysia and detained for carrying 11 rounds of .32 bore.

"He said it were of his licensed revolver and he carried them accidentally. We are also verifying his claims," an officer said.
