Police are appealing for public assistance to help locate an 18-year-old male reported missing from Logan Reserve.

Police and carers hold concern for his welfare due to a medical condition.

Acting Commissioner and Queensland Disaster Coordinator Shane Chelepy told Peter Fegan on 4BC's Special Coverage, "We've got Swiftwater Rescue Crews, we've got our Police Search and Rescue Coordinators out there in that area, and we're appealing to the public who could have very valuable information if anyone has seen Caleb at all."
