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," said Kevin Crowley, a Wilfrid Laurier University spokesman. 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 yesterday'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."
Waterloo police say that details of the arrest and potential charges are limited, and investigators are consulting with other law enforcement agencies.
