Calgary police have laid more than 100 charges against 17 people — including nine youths — following a months-long investigation into a rash of overnight break and enters across the city.The investigation was launched after police warned in June about a surge in residential break-ins occurring while homeowners were asleep. The crimes, which date back to August 2024 and peaked in May and June 2025, affected neighborhoods across Calgary. Investigators believe the suspects were working together in a coordinated effort to target homes.Search warrants were executed at three southeast Calgary residences, and six additional judicial authorizations were granted as part of the operation. Police say the suspects were known to one another and shared a common plan.The charged individuals include eight adults and nine youths. Offences range from break and enter, theft, and possession of stolen property, to resisting arrest, drug trafficking, and dangerous driving. Some suspects also face multiple counts of failing to comply with court orders. Because of their age, the names of the youths cannot be released under the Youth Criminal Justice Act.Police say the youth offenders will be engaged through the Serious Habitual Offender Program (SHOP), a community-based intervention effort aimed at reducing repeat offences among youth aged 12 to 24. SHOP monitors around 80 young people at a time and focuses on prevention, enforcement, and community support.“This was a large and complex investigation that required coordination across several areas of our service,” said Staff Sgt. Rob MacKenzie of the District 4 General Investigations Unit. “This is a great example of impactful police work and investigative techniques, as we were able to arrest and charge 17 individuals responsible for victimizing Calgarians.”Police say suppression strategies are in place to prevent further crimes and encourage anyone with information to call 403-266-1234 or contact Crime Stoppers anonymously.
