Officers now believe that a second motorbike (pictured below) was involved in the incident before making off from the scene and police would like the rider to come forward and speak with them as they may be able to assist with enquiries.

A man in his twenties suffered with suspected head, pelvic and leg injuries. He remains in hospital in a “critical but stable” condition. 

A 20-year-old man arrested in connection with the incident was released under investigation.  

The Range Rover believed to be involved made off from the scene.  

Officers are again appealing for CCTV and dash cam footage and they also want to speak to any witnesses.
