Another swing occurred on a road in Gatineau park, Monday evening.
Fortunately, no one has lost their life, in contrast to the incident dramatic, which claimed the lives of two twenty-somethings, last week, on the promenade Champlain.
The incident Monday occurred on the same trip, to the north of Kingsmere lake, shortly before 18h.
Two women of 17 years and two men of 18 years of age were injured. The victims were transported to the integrated Centre of health and social services (CISSS) in the Hull sector.
Their injuries do not put their lives in danger.
Like last week, the royal Canadian mounted police, which has jurisdiction to patrol the area, is terse, and is not confirmation of any cause that can explain the cause of this lurch.
