ST. LOUIS – A student has been suspended and two guns have been confiscated after they were found on the Washington University campus.

According to an email from Chancellor Mark S. Wrighton to students and staff, the school received a tip about potential weapons on campus. After receiving the tip, they conducted a search of the Phi Delta Theta fraternity house where they found an AR-15. They also found a handgun in a vehicle parked in a nearby parking garage.

The email said both guns belonged to a member of the fraternity, but there was no threat to the community.

The email said the weapons "put at risk members of our university community and is a very serious violation of university policy." The student was temporarily suspended and removed from campus until a formal judgement can be made.

The Washington University chapter of Phi Delta Theta was suspended last year after a possible hazing incident from Spring of that year.

A statement from the school said the fraternity is now permanently suspended and all members have been asked to vacate the house.

Earlier today, after receiving information about potential weapons on campus, the University conducted a search of the Phi Delta Theta fraternity house and discovered an AR-15 semiautomatic weapon in the house, and a handgun in a vehicle parked nearby. Both weapons belonged to a member of the fraternity.

This is a very serious violation of university policy that put at risk members of our university community. Effective immediately, the university has temporarily suspended the student involved pending completion of formal adjudication. Although there was no immediate threat, we took necessary and appropriately swift and decisive action to maintain the safety of all members of our community.

Based on unrelated violations of a previous temporary suspension, the university has informed members of Phi Delta Theta that the fraternity now is permanently suspended. The university has asked all members of the fraternity to vacate the house immediately.
