The boy who died after being hit by a minibus in Monmouth has been named as seven-year-old Samuel Barker.
The incident happened on Monday on the A466 Hereford Road between Withy Lane and Buckholt just before 4pm.
Police confirmed the boy was pronounced dead at the scene. The driver of a bus, a 45-year-old from Gloucester, has been arrested on suspicion of causing death by careless driving.
Samuel's family said he had a "glowing personality and a lightly zany sense of humour".
A West Midlands Ambulance Service spokeswoman said: “Ambulance crews arrived to find a pedestrian, a boy, who had been involved in a collision with a bus.
"Sadly, nothing could be done to save him and he was confirmed dead on scene.”
The boy's school have paid tribute to him, describing their pupil as someone who was "always smiling" and "full of character and energy".
The A466 was closed in both directions after the crash, although traffic and travel information service reported that it reopened at around 9.30pm.
It is believed several emergency vehicles attended the scene.
A Welsh Ambulance Service spokesman said: “We were called yesterday (13 January, 2020) at approximately 3.44pm to reports of a road traffic collision involving a vehicle and pedestrian on the A466, Monmouth.
"With the support of West Midlands Ambulance Service, we responded with one emergency ambulance and two rapid response vehicles.”
Police said officers are investigating the circumstances surrounding the incident and are appealing for anyone who may have witnessed the collision or if anyone has dash cam footage to contact Gwent Police.
Leader of Monmouthshire County Council, Cllr Peter Fox, said: “I would like to offer deep and sincere condolences to the family and friends of this little boy from everyone associated with Monmouthshire County Council.
"It is just not possible to put into words how sad we feel. We are here to help and will be supporting the school, children and colleagues over the coming days and for as long as is necessary."
Catherine Jones, Head Teacher of Osbaston Church in Wales School said the school was "hugely saddened" by what has happened.
