Dalhousie University says the police found nothing in relation to a weapons complaint at the Killam Library.

The library has returned to normal operations after a shelter in place was announced for the building.

At about 2 p.m., police said they responded to a phone call about a gunman in the Killam Library area, according to a Halifax Regional Police news release.

At 2:12 p.m., the school notified people through DalSafe that people at the Killam Library should shelter in place because of a weapons complaint.

At about 2:19 p.m., the school told people to stay clear of the library and police are checking each floor.

“There is no known threat but police are searching based on unconfirmed information,” the school said.

At 2:27, the school clarified the shelter in place was only related to the library.

The school said evacuation was not ordered for the library because a mass exit would “not be helpful” to the police officers searching the building.

However, the school said people are free to leave if they choose and go to other buildings nearby.

At 2:39 p.m., the school said that police found nothing during the search of the building.

Police said they didn’t find the man in the building or in the area, and there were no other reports related to the gunman.

“We recognize the significant disruption and upset an event like this will cause. Students are reminded of the supports available through Student Health and Wellness. Faculty and Staff may opt to speak to Employee Family Assistance program or their manager,” the university wrote on the DalSafe app.

The school adds, “Police will continue to investigate the source of the suspicious telephone call.”

No one was reported injured during the incident.

Police say they will remain in the area as a “precautionary measure.”
