Toddler Killed In Crash Near Wimborne
A man, arrested after a car crash in Dorset which killed a two-year-old girl, has been bailed by police.
At 9.20pm on Sunday (31 May), a blue MG car with five people inside was travelling on the B3078 Wimborne to Cranborne road - from Horton toward Wimborne - when it left the road and collided with a wall before landing on its roof.
A two-year-old girl from the Wimborne area died. Her next of kin have been informed and the coroner notified.
A nine-year-old boy, also from the Wimborne area, suffered serious and potentially life-threatening injuries and was transferred to Southampton General Hospital.
An 11-year-old boy, from Corfe Mullen, suffered bruising and was taken to Poole Hospital for treatment.
The driver of the car and a 28-year-old female passenger, from the Wimborne area, were treated for minor injuries and shock.
The driver, a 28-year-old man from the Wimborne area, was arrested on suspicion of causing death by dangerous driving. He has now been released on police bail until mid-August pending further enquiries.
The B3078 was closed between the Witchampton junction and the Horton Inn junction to allow collision investigators to carry out a thorough examination of the scene.
Inspector Matt Butler, of Dorset Police’s Traffic Unit, said:
“This was a tragic incident and specially-trained family liaison officers are supporting the family at this difficult time.
“I am appealing to anyone who witnessed this collision, or the manner of driving of the MG prior to the incident, to please call me on 101.
“All calls will be treated in strict confidence.”
