Police say they have six young men in custody tonight apparently in connection with the brazen invasion at a Toronto high school. Four masked and armed youths invaded a classroom at Thistletown Collegiate during the mid-afternoon. They brandished at least one weapon and stole cellphones from two girls. One girl had a gun held to her head. When another student fled the classroom he was chased and shot at. No one was injured. The four fled the scene in a stolen blue Toyota which has apparently been recovered in conjunction with the arrests.
