Federal marshals and local authorities raided and seized three University of Virginia fraternity houses, arresting three students on charges of drug distribution.

Nine other students were also indicted and were being sought after the Thursday evening raids, which stunned the campus, authorities said."I think anyone who lives in a university environment lives a bit of a sheltered life, so this is a shock. You expect underage drinking, but these are federal agents here. This isn't a small matter," Philip Korologos, a law student, said as he watched federal, state and local officials searching through the three fraternity houses Thursday.

Charlottesville Police Chief John Bowen said the joint federal-local drug task force arrested three students and was seeking nine others on drug-distribution charges.

Around 8:40 p.m., 40 federal, state and local officers raided the Delta Upsilon, Phi Epsilon and Tau Kappa Epsilon houses. Bowen said the task force had been investigating drug traffic on campus since last August.

E. Montgomery Tucker, U.S. attorney for the Western District of Virginia, said the arrests show "there are no safe havens, no safe places, to conduct illegal drug trafficking."

At a news conference Friday morning, police displayed 12 bags of marijuana, three bags of hallucinogenic mushrooms, one bag of LSD tabs, a marijuana growing system and various drug paraphernalia seized from the fraternity houses.
