Since 2018, more than 75% of vehicle thefts and 49% of home invasions in Northville occurred due to unlocked property. To remind residents to not give thieves an open invitation to steal your valuables, when an officer on patrol observes a residence with an open garage door in the middle of the night, unattended packages on a porch or high valued items left in a vehicle, they attempt to make contact with the owner. If they're unable to make contact, a public information “Lock it or Lose it” card is provided after they attempt to resolve the issue.
