 Police are investigating an incident that occurred at the Caravonic around about on the Captain Cook Highway at about 4.51 this morning. Now a male person parked a vehicle on the roundabout which was headed in the wrong direction and police attended there to see what was going on and at which point we're alleging that this male attacked two officers. Now additional officers attended from Smithfield and Cairns and various use of force options were used in order to try and subdue the man. These included capsicum, spray, tasers and other hand-to-hand restraints. Now they eventually did manage to restrain him. One of the officers was injured. He did sustain a hand injury as a result and the man is now assisting police with inquiries. Charges are expected to follow but we are appealing to witnesses. We know that there was a number of people who were on the roundabout traversing that roundabout in the early hours of this morning and they were aware that they observed the incident but nobody spoke with police. We're asking for those people to make contact and they can do that by crime stoppers on 1800 triple 3 triple 0.
