Ten victims were referred to the Tengku Rafian Siak Regional Hospital for further treatment. The remaining six victims underwent medical observation and were discharged as their conditions were deemed stable.
Based on initial examinations at the referral hospital, one victim suffered severe injuries, six had moderate injuries, and three had minor injuries. The injuries included lacerations on the head and face, bruises, back and leg pain, and suspected fractures.
As of Saturday afternoon, there were no reported fatalities. However, one victim was further referred to a hospital in Pekanbaru for additional medical treatment.
