Montreal police are investigating after shots were apparently fired in a Mercier–Hochelaga-Maisonneuve schoolyard Sunday night.

According to SPVM spokesperson Caroline Chèvrefils, the incident occurred at around 10:15 p.m., when authorities received "several" 911 calls about gunfire near the intersection of avenue Pierre-de-Coubertin and avenue de Carignan.

Officers didn't find any suspects or victims on the scene, Chèvrefils said, but a K-9 unit later found shell casings on the ground.

Citing preliminary information obtained by police, the spokesperson said it looked like "more than one" suspect fired shots in a schoolyard before fleeing in a vehicle. She did not identify the school, but the Louis-Dupire Elementary School and Édouard-Montpetit High School are nearby.

Investigators and crime scene technicians later descended upon the scene. There were no arrests as of early Monday morning.
