In the first incident, one passenger travelling to New Delhi by GoAir flight was found carrying two bullet shells in his bags. In the second incident, a Mangalore-bound passenger, travelling by SpiceJet, was found in possession of one empty cartridge, a senior CISF official said.
"The empty cartridges were detected during screening of their luggage at the airport," he said.
"The cartridges detected were not live and cannot be fired. But since they are a part of ammunition, they cannot be carried on board," the official said.
The empty cartridges were seized and the passengers were allowed to go, the official said.
