University Police sent an email on Friday updating the campus community on its investigation of an incident where a noose was found in a fraternity house.

The noose, found on April 27 inside the University of Maryland’s Phi Kappa Tau chapter house on Fraternity Row, was reported to be in the kitchen, the email read. Police believe the incident occurred between 1:06 and 1:10 p.m.

University Police conducted a video review of cameras around the outside of the house and Fraternity Row but found no evidence, according to the email.

Detectives have interviewed fraternity members and others who may have had knowledge of the incident, and they will continue to conduct follow-up interviews, the email read.

The message comes after members of ProtectUMD arranged a sit-in at the Main Administration Building on Wednesday to demand this university take action and provide a response to the incident, as well as other recent incidents threatening minority students on the campus.

ProtectUMD presented three demands to the university administration during the sit-in: immediate responses to hate speech by this university, diversity training for all SGA-recognized and Greek organizations and the creation of an external review board to investigate hate bias incidents that occur on the campus, according to a ProtectUMD news release.
