All east campus residence halls, commonly known as the Chi-5 dorms, went under lockdown after police received an unconfirmed threat at approximately 10:30 p.m. Tuesday.

According to UCPD Sgt. Dan Wilson, police received a report that a screaming noise and gunshot sound were heard near the east campus dorms at about 10:29 p.m.

Wilson said at 10:58 p.m. that “we’re not able to find any type of evidence that there was a gunshot.”

UCPD would likely rule the lockdown a false alarm if they did not find any evidence pointing to a shooter, Wilson said.

Police followed up on the initial report and conducted checks of the area surrounding the east campus residence halls.

Police determined that the threat was “false and unfounded” after searching the area, according to Wilson. He said there is no safety concern to the public as of 11:45 p.m., and the screaming was unrelated.

“We were able to track down that person and confirm that the person was okay and not related to the gunshot,” Wilson said, adding that the residence halls locked down the buildings due to their own policy.
