Seven live cartridges were found from the Ferozeshah Kotla stadium in New Delhi, barely two hours before the commencement of the one-day cricket match between India and Australia on Saturday.
A senior police official said there was 'no security issue' involved in the recovery as they suspect that the cartridges were that of a security personnel posted at the stadium for the match.
The ammunition wrapped in paper were retrieved from a rest room in the second floor of the stadium by the personnel of bomb detection squad and dog squad around 12:30 pm, two hours before the start of the match.
"We suspect that the cartridges were that of a security personnel who was careless on handling it. We are trying to ascertain whose cartridges they were," the official said.
Police are also investigating whether any private person had brought the cartridges inside. "We are not ruling out anything. We are probing all angles," the official said.
Asked whether the cartridges were those allotted to security personnel, the official refused to comment.
The police have asked authorities to provide a list of people who work in the stadium and also about those who have access inside.
According to the official, the matter was kept secret as it could have created panic among people on the day of the match.
A case was registered at the IP Extension Police Station under relevant sections of the Arms Act. However, no arrest has been made so far.
