An expelled 16-year-old student entered a Christian high school during chapel and put a pellet gun to the pastor's head before he was tackled and arrested, AP quoted witnesses as saying. Regina Police Service spokeswoman Lara Guzik Rostad said police received an emergency call Tuesday morning and arrested the teen shortly after. Police said they recovered a pellet pistol. Alex McNair, a student, said the gunman put the gun to the pastor's head and told him to read a letter he wrote about his expulsion from the school. Almost all of the school's 400 staff and students were in the chapel, McNair said in a message to The Associated Press via the Internet social networking site Facebook. The school was evacuated. McNair said teachers opened the doors and students tried to leave quietly. McNair said the gunman's letter was about how he was getting bullied.
