London Road Assault


Broadcast Time:        2:45 p.m.                        Date: March 28th, 2024

On the 4th March 2024, the Sarnia Police Service attended an Unwanted Person call in the area of 180 College Ave N, in the City of Sarnia. Information was that a group of youth were looking to cross from London Road School to the Boys & Girls Club of Sarnia-Lambton after-school program at the Lochiel Kiwanis Centre.

As the group was waiting to cross a female, behaving erratically, ran onto the road and started to direct the group to cross. As the group was crossing the road, the female approached them and grabbed one of the youths, causing scratches. The staff quickly intervened and called the Sarnia Police Service. The victim did not need medical assistance regarding this assault. The suspect was not known to any of the involved youth or staff.

Officers obtained a description of the suspect, searched the area, and located her nearby. Police observed her to be in obvious medical distress for which she was apprehended by police and taken to a medical facility for treatment. It is believed that her medical state observed at the time was a contributing factor in the erratic behavior and earlier assault. She was released from police custody for necessary medical treatment and the SPS Criminal Investigations Division was assigned to continue the investigation of the earlier assault.

Police identified Sarnia resident Harmony MONCRIEF, 28 years old, as being the person responsible. On March 12th she was placed under arrest for the criminal matters and released with conditions on the following charges:

  • 1 count of – CC 266 – Adult Assault
  • 1 count of – CC 733.1(1) Adult Fail to comply with Probation Order

Investigators believe this assault was an isolated incident, not planned nor targeted. The accused in this matter was involved in other nearby incidents on that same date, consistently demonstrating the same erratic and irrational behavior.
