A lockdown at Wilfrid Laurier University has been lifted but authorities say they are still seeking the person responsible for an online threat against the school.

The campus was shut down at 6:00 am on Friday and students and faculty were not allowed anywhere on campus after administrators were tipped off to the threat overnight by the F-B-I.

The lockdown was lifted at 11:30 am.

Waterloo Regional Police say the threat was made in an anonymous post on the online forum 4chan, and noted it used similar wording as a threat made before a deadly school shooting in the U.S, earlier this month.

They say it appears whoever posted the threat was not in Waterloo.

Police are continuing to work with the R-C-M-P to find the origin of the threat.
