For the second straight Friday, police officers are more visible around the Waterloo campus of Wilfrid Laurier University.

Waterloo Regional Police said Friday morning that a photo posted to Snapchat “raised concerns” about what could happen at the school.

The photo, which police made public, appears to show a man holding a rifle with the phrase “Tell Isis to find me in the science buildin (sic).”

The man’s face is obscured by an emoji, and a flame emoji covers his chest.

Police say the weapon in the photo is a replica, but they hope to track down the person who posted it – who may face a charge of mischief.

“We’re asking for any information that may assist us in identifying the person or persons responsible for posting this image,” said Staff Sgt. Mike Haffner.

Laurier’s Waterloo campus remained open Friday – a different scenario than one week earlier, when a lockdown was ordered due to a threat made on the 4chan message board.

“Police were satisfied that there wasn’t an immediate threat to the Laurier campus,” said school spokesperson Kevin Crowley.

Crowley said police had searched the building and two neighbouring facilities, after being tipped off to the Snapchat by two citizens.

“It alarmed and disturbed the two individuals that had seen it,” he said.

Daniel Ransem, a 22-year-old resident of the United Kingdom, faces a charge of malicious communications under British law in connection with last week’s threat.

In an interview with CTV News, he said that he was “just trying to fit in” with the online community and didn’t expect his post to be taken seriously.
