AMHERST - University of Massachusetts police are looking for two suspects who reportedly threatened two students with a gun during a botched drug deal outside Dwight Hall, a freshman dorm on the northern part of the UMass campus.

According to UMass police, officers responded to a report of a physical altercation on the 3rd floor of Dwight just after 3:30 p.m. Wednesday. They found nothing at the scene, but a witness later directed officers to talk to two students inside a dorm room in the residence hall.

The students told police that they had been assaulted during an attempted marijuana transaction. The altercation began inside the hall and spilled out into the parking lot where the two suspects displayed a gun.

They got into a red car and drove away from the scene.

The two students did not need medical attention.

The suspects are described as two college-age white men. One has short blond hair and is around 5 feet, 10 inches and facial hair. He was wearing a white T-shirt and blue jeans. The other was roughly 6 feet, 1 inch tall and thin, with brown hair. He was wearing a bright red sweatshirt, blue jeans and gray or white Nike sneakers.

Police are tracking several leads and are reviewing video footage. They ask that people who see either suspect to call campus police at 413 545-2121.
