INCIDENT: Marijuana Plant Seizure at Local Residences

ONTARIO - Ontario Police served search warrants at three different homes in the same neighborhood resulting in the seizure of thousands of marijuana plants.

On April 12, 2022, Ontario Police Officers served search warrants at two homes in the 4100 block of S. Canal Way and one home in the 2900 block of E. Grafton Street. The warrants resulted in the seizure of 2650 marijuana plants. Each of the homes were vacant at the time police arrived and no arrests have been made.

Upon entering one home, a large gas leak was discovered which threatened the safety of our officers and the surrounding community. Personnel from the Southern California Gas Company and Southern California Edison responded to assist in rendering each location safe.
