Witness appeal following serious collision in Chertsey

We are appealing for witnesses following a serious collision in Chertsey.

Officers were called to the M25 clockwise carriageway at 5.45pm this evening (Saturday, 13 June) following a collision between the riders of two motorcycles. The collision occurred on the slip road at junction 12 leading to the M3.

A man in his 30s and a man in his 40s, both riders of the motorcycles, sustained life threatening injuries and were taken to hospital by air ambulance. Their next of kin are aware.

The M25 clockwise carriageway was closed between junction 11 and 12 for several hours whilst emergency services responded to this incident and has since reopened. The slip road from the M25 junction 12 clockwise carriageway onto the M3 remains closed at this time.

We are asking anyone who may have witnessed the collision, or who may have CCTV, dashcam, or helmet cam footage that may have captured all or part of this incident, to get in touch.

We are particularly interested in tracing the movements of the riders prior to the collision, and would like to speak to anyone who saw a group of motorcycle riders on the M25 in the minutes beforehand.
