Saskatoon Police say they have seized more firearms from the home of a boy who brought a loaded gun to school Thursday.

The .45 calibre handgun went off in a classroom. No one was hurt but parents said many youngsters were shaken by the episode.

'We have questions about how did an eleven-year-old boy end up with a handgun and take it to school?'—Saskatoon police spokeswoman Alyson Edwards

On Friday police said their investigation took them to the 11-year-old's house where they found seven long guns and another hand gun.

Alyson Edwards, a spokeswoman for Saskatoon police said an officer with expertise in firearms is looking into how the weapons were stored.

"He's going to try to determine what the storage situation was, how that gun came to be loaded, are they licensed, do they meet the requirements. That kind of thing," Edwards said Friday. "That's going to take a few days."

They are also trying to find out who loaded the hand gun that the boy brought to St. Peter School, reportedly to show his friends.

"Obviously we have questions about how did an eleven-year-old boy end up with a handgun and take it to school," Edwards said. "And not only that, but the gun was loaded."

It was in a back-pack when it fired with the bullet going into a locker at the back of a classroom.
