THE FOOTAGE from a helicopter trying to find the car that dragged PC Andrew Harper to death has been played to the jury. 

The helicopter, deployed by police on the night of August 15, can be seen hovering in the skies as it focuses on Four Houses Corner Caravan Site in a bid to find the Seat Toldeo at the center of PC Harper's murder investigation.

In the video conversation between officers and helicopter operators can be heard as they all try to pin down the location of the car. 

When they find it, the helicopter operator says: "I've got a Seat I think, very, very hot. Number of males around it." 

Another officer says: "Please be mindful that these people have already seriously injured one of our officers." 

The trial continues.
