A group of figures are gathered a few meters away, behind two police patrol cars also in the ditch, many clearly wearing police uniforms. The video, provided to CTV News by Jordan Brandon, was taken from Brandon’s car as he drove past a large police presence camped on the other side of the highway. Taken north of Rosthern, Sask., south of Duck Lake. At least 10 police patrol cars can be seen in the footage, blocking off the motorway, while a helicopter flies over the scene. An earlier alert issued Wednesday said a person allegedly armed with a knife had been spotted in Wakaw, Sask., and was believed to be traveling in a stolen white 2008 Chevrolet Avalanche. Police said Miles Sanderson, the prime suspect in the case, was arrested around 3:30 p.m. Wednesday, according to an update canceling an emergency alert that was first raised in the province Sunday morning after a rampage involving knife to James Smith Cree Nation. Sanderson, 30, and his older brother were identified on Sunday as suspects in the stabbing attacks. Damian Sanderson, 31, was found dead in James Smith on Monday near a home, with injuries that police believe were not self-inflicted.
