Stuart Cunningham-Jones was sitting on the upper deck of the bus

Stuart Cunningham-Jones, 12, died in December 2002 when the double-decker he was on veered off a road in the Vale of Glamorgan and hit a tree.

An inquest found that the driver may have been distracted by some pupils.

In June 2003 it was decided there was not enough evidence to charge anyone. Stuart's father David said the family was delighted by the new inquiry.

Mr Cunningham-Jones said the family hoped that officers would follow several issues raised at the inquest.

The vehicle in which Stuart died had been taking the youngsters home from Cowbridge Comprehensive School.

Stuart, who was sitting at the front on the top deck, died at the scene and 30 of the 72 children on board were injured in the crash near the village of Ystradowen.

It later emerged that a fingerprint found on the bus's steering wheel matched that of a 14-year-old pupil on board the bus.

The bus driver, Reginald Davies, broke down at the inquest as he explained that he had stopped the bus once because he felt some pupils' behaviour was becoming dangerous.

The Vale of Glamorgan Council has issued a statement saying: "The council has not been involved with the police review, which it is understood was an internal matter for the police themselves."

"It has, however, conducted its own review of procedures and practices in relation to school transport and is currently implementing a series of recommendations."

The authority has also said it planned to use anti-social behaviour and banning orders to protect pupils.

Stuart's parents, David and Joanna, have campaigned for improved safety for children who travel on school buses, founding a campaign in Stuart's memory.

At his inquest in Cardiff in January this year, Mr and Mrs Cunningham-Jones also called for the Crown Prosecution Service decision not to charge anyone over the incident to be reviewed.

Last month a video addressing the dangers of distracting drivers had its official launch.

Nearly 100 people, including Health Minister Jane Hutt, bus manufacturers and bus companies, attended the launch at the Welsh assembly in Cardiff Bay.
