Police say they got a weapons complaint late Thursday night about a residence in the southeast part of the city.
They responded with patrol and tactical team officers, a canine unit, police helicopter, and emergency medical services, and set up a command post.
But it turned out the residents of the house were the victims of "swatting."
Police say swatting is a false report called into 911 about a serious incident often involving weapons and suggesting lives are at risk.
SWAT, the acronym for Special Weapons and Tactics, is commonly used name for special law enforcement units called out to high-risk operations.
Edmonton police say it's difficult to figure out where the call comes from and often these calls involve video gamers.
“This is a crime of public mischief,” says Insp. Regan James. “These false calls can put a significant strain on emergency services and resources and affect other legitimate calls for service.”
Police continue to investigate.
