It's interesting that the Sri Lankan cricket team who were on tour in Chch had been dropped off by bus at the Mosque to pray, heard gunshots and ran to Hagley Park. They could have been in the Mosque if they arrived a few minutes earlier or on the street for him to shoot a few minutes later.
It was the Bangladesh cricket team that was in Christchurch at the Mosque.
Not the Sri Lankan one!
Here is a very detailed account from one of the Bangladesh teams players of what happened that day.
...We returned to the team hotel and went straight to Riyad bhai's room. We started to watch the shooter's video. The players started to weep, like they were doing in the dressing room.
