A missing stop sign may have contributed to a collision at a Guelph intersection early Sunday morning, prompting a police investigation.

According to Guelph police, three males are believed to have removed the traffic sign at Cole Road and Scottsdale Drive sometime late Saturday night.

The absence of the sign went unnoticed by at least one motorist. Around 12:30 a.m., a vehicle travelling through the intersection collided with another car heading southbound after its driver failed to realize a stop was required.

Police later located the missing sign propped against a nearby residence and had it put back in place. While the crash caused extensive damage to both vehicles, no serious injuries were reported.

Investigators are seeking information from anyone who may have witnessed the sign being removed or has details that could help identify those responsible.
