Seven live cartridges were found from the Ferozeshah Kotla stadium in the capital where a one-day cricket match between India and Australia was held two days ago, police sources said on Monday.
The cartridges were retrieved from inside the stadium on Saturday after the match between India and Australia, a senior police official said.
Police believe that the cartridges were that of a security personnel posted at the stadium for the Saturday match between the two countries, he said.
"There is no security issue involved in it. However, we are investigating the matter," the official said.
