POLICE investigating a serious collision in Winterbourne Bassett near Swindon last week are trying to trace a motorcyclist and cyclist who they believe could provide important information.

As previously reported, a Ford KA Cabriolet overturned several times after striking a grass verge whilst travelling south on the A4361 near Bowman’s Wood last Tuesday, March 18.

The driver of the Ford KA, a 40-year-old man from Swindon, suffered serious chest injuries and was airlifted to Frenchay Hospital in Bristol where he currently remains in a serious condition in intensive care.

Officers are particularly keen to speak with both a motorcyclist and pedal cyclist who were travelling between Broad Hinton and Salthrop, towards Wroughton at the time of the collision.

It is believed that both riders witnessed the KA and a black Honda Civic, including their manner of driving, travelling together immediately prior to the collision.

The riders, or anyone who has any information about the collision are asked to contact PC David Williams of the Serious Collision Investigation Team (SCIT) at Wiltshire Police on 101 as soon as possible.

Alternatively people can contact Crimestoppers anonymously on 0800 555 111.
