After a massive manhunt lasting hours, Canadian police arrest a man they believe shot dead three officers, wounding two more.

The men were killed while responding to a report of an armed man spotted in northern Moncton.

"He had a couple guns. On his back a crossbow. Knives all over his pants. All the ammo geared up."

"He just had the most blank look on his face that he was on a mission, ready to do something. My stomach dropped. I had the worst feeling in my gut."

Hundreds of police cordoned off a large area of New Brunswick on Thursday, warning residents to stay in their homes.

This man is believed to be responsible.
