A lorry driver arrested after a three-year-old boy was killed on a pedestrian crossing has been released under investigation, police have said.
The boy was crossing North Street in Wareham, Dorset, with his family on Thursday morning when he was struck by an articulated Sainsbury's lorry.
The toddler, who has not been named, sustained very serious injuries and was taken to Dorset County Hospital for treatment but was pronounced dead a short time later.
A 43-year-old man from Basingstoke who was arrested on suspicion of driving offences has now been released under investigation, Dorset Police said on Friday.
Inspector Matt Butler, of the force's traffic unit, said: "The family are continuing to be supported by specially trained officers and have requested privacy at this very traumatic time.
"We are continuing to investigate the circumstances of the collision and are still appealing to anyone who witnessed the incident or saw the manner of driving of the lorry immediately before to please come forward.
"I am also keen to hear from any motorists who were travelling along North Street at the relevant time and have dashcam fitted in their vehicles."
North Street was closed between the junction with West Street and the roundabout at the junction with the A351 while collision investigators examined the scene.
Mike Coupe, chief executive officer of Sainsbury's, said: "This is an absolute tragedy and we will do everything we can to support the family."
