A fast response ambulance car driver has been suspended after two pedestrians were hit and left with serious injuries as he sped to an emergency call.
The driver stopped to treat the two casualties following the accident on the A40 by the GCHQ building in Cheltenham just after midnight on Sunday. He then called two ambulances to rush the casualties to hospital in Gloucester.
A 32 year-old man from Bristol was later transferred to Southmead Hospital in Bristol with serious head injuries.
The second man, aged 30 from Cricklade, Wiltshire, remains at Gloucestershire Royal Hospital with serious leg injuries.
Police officers closed the road for five hours to conduct an initial investigation and South Western Ambulance Service Trust said it was carrying out a "thorough investigation".
