Police in London, England have charged a man who allegedly posted an online threat against Wilfrid Laurier University.
The man was arrested in London on Friday, and the charge laid Saturday.
The 22-year-old man, identified by police as Daniel Ransem, will appear in court Monday.
He faces a charge of malicious communications.
The U.K.'s Malicious Communications Act makes it illegal for anyone to send a threat with the intent to cause distress or anxiety.
The man's connection to Wilfrid Laurier, if one exists, is unknown.
"I think that knowing that there wasn't a local threat will be a comfort to students and staff," Kevin Crowley, a Wilfrid Laurier University spokesman, said Saturday. He said there were few people on campus at the time of the lockdown, which lasted nearly six hours.
A spokesperson for Waterloo police says that because the threat came from the U.K., London police have jurisdiction.
Waterloo police compared Friday's threat to a warning posted before a shooting earlier this month at an Oregon college that left 10 people, including the shooter, dead.
A photo shared on Twitter showed a post that featured an image of a frog holding a gun and read: "Don't go to laurier science building hall tomorrow. happening thread will be posted in the morning."
A post that preceded the Oregon shooting read: "Don't go to school if you are in the northwest. happening thread will be posted tomorrow morning."
