The Saskatoon Fire Department received a call from an alarm company shortly after three this morning (sat) for a fire alarm that went off in the 200 block of Avenue K South. The first arriving crews found not signs of fire at the four storey building. Fire crews say entry was made into the building and a pull station was identified in which a person had intentionally pulled the alarm. Saskatoon Police located and handled the person responsible for the misuse of the fire alarm system. Firefighters reset the alert system prior to leaving.
