An event that concerned Saskatoon police has been cancelled.

Saskatoon's 1st Annual Purge Walk was scheduled to be held Saturday night at River Landing. Based on the horror movie franchise, a poster for the event asked participants to "Dress as your favourite purger or create your own terrifying look."

Now, Saskatoon police say the event has been cancelled.

"We have been contacted by the event organizers who stated that they are canceling this event," read the release. "They stated that the way it was perceived is not what they had intended."

Police were concerned about the event, and said so on Facebook.

"This event is not endorsed by the SPS," read the thread. "We caution those considering participating of the hazards of running around in public areas with weapons (fake or not)."

Organizers said the event was supposed to be a fun, silly event, and are shocked it has received this much attention. They said the safest thing to do would be to cancel the walk.

"We're just kind of scared," said co-organizer Amanda Walter. "We don't know what people will do, and like, all this media, we don't know how it's going to go. The situation is now out of control."

Posters on the group's Facebook page remain divided.

Police plan on patrolling River Landing Saturday night, to make sure there are no issues.
