New Delhi, March 5 (IANS) Commonwealth Games Federation (CGF) chief executive Mike Hooper Friday said the successful staging of the Commonwealth Shooting Championships and the ongoing Hockey World Cup will help reduce security fears among some of the participating nations for the October 3-14 Games.

"The chef-de-missions of all the 71 nations are arriving here next week and there will be presentations by the Delhi government, the Delhi Police about the security and other aspects," Hooper told reporters on the sidelines of the Hockey World Cup here at the Major Dhyan Chand Stadium while cheering for his national team - New Zealand.

"I think the security has been fantastic. It's almost impossible to breach this kind of security ring.

"We have had a successful Commonwealth Shooting Championships which went off without any untoward accident. I think all reservations about the security will be put to rest once the delegates come over to Delhi and have a look at the progress themselves," Hooper added.

The New Zealander said the participating teams had reservations before coming for the World Cup, but after arriving here all their doubts have been dispelled.

"Yes, there were players and teams which had a few reservations about the security here. But ever since the teams have arrived here, I am sure no one has had any problem with the security,'' he said.
