Calgary Police say five schools were placed in lockdown mode Monday, after they each received a voice generated "Swatting Call"
Police said the schools received various threats, including one suggesting there were explosives planted in the school. Another stated an armed person was coming to the school with the intention of carrying out a shooting of some kind.
The schools were locked down, but none was evacuated.
CPS say that none of the threats were legitimate.
Swatting is when an individual makes a prank call to emergency services in an attempt to bring a large number of armed police officers to a particular address.
