The assault of a gay man by a group of Salisbury University students in Maryland has drawn national media attention since last week. So far, 12 men ages 18-21 have been arrested in the brutal attack. The students allegedly lured the man to an apartment because of his “sexual preferences,” according to local police.

Sigma Alpha Epsilon expelled the students in their organization who are accused of being involved in a hate crime incident in October at Salisbury University in Wicomico, a spokesperson for the national organization said Monday.
