New York City authorities say five Columbia University students are charged with selling drugs on campus and at fraternity houses.† According to the Associated Press, Special Narcotics Prosecutor Bridget Brennan and Police Commissioner Raymond Kelly said Tuesday that the students and three off-campus suppliers have been arrested and indicted. The five-month investigation began in July. Authorities say undercover officers bought cocaine, marijuana, ecstasy, adderall and LSD. In some cases, the LSD was in breath mints and candy. Authorities say one of the off-campus suppliers plotted to kidnap a pair of rival cocaine traffickers.
