Witnesses tell police a 16-year-old student at Madison West High School was “waving a taser around” and shouting obscenities Wednesday afternoon. Police were called to the school at about 2:00 P-M, they took the student into custody. The teenager tried to run away when officers approached, but he was caught after a brief foot chase. He faces charges of possession of a dangerous weapon on school property, disorderly conduct, carrying a concealed weapon and resisting. Nobody was injured during the disruption. The suspect was taken to the Dane County Juvenile Reception Center. His name won’t be released due to his age.
