A six-year-old boy has been left with brain damage and a paralysed face after an arcade game toppled over and crushed him on a family holiday.

Oscar Donnelly was also left with a rare form of diabetes after he was knocked unconscious by the 6ft darts machine which pinned him to the ground in the Spanish resort of Lloret de Mar.

The schoolboy was staying at the Aparthotel Costa Encantada with his two older brothers and parents Luke Donnelly, 30, and Samantha Matthews, 29, from Cardiff, who have now launched legal action against the hotel.

They say staff failed to anchor the arcade game securely to the floor, and claim it was tipped on top of their youngest son by the vibrations from a nearby punchbag machine in the play area of the hotel.

One of his brothers witnessed the incident during the last few hours of the family's 10-day holiday last September and alerted the couple who found their son unconscious with his head covered in blood.

Miss Matthews, a care worker, said she feared her son had died after he was admitted to a hospital in Girona.

She said: "We were taken up to intensive care, still not knowing if Oscar was alive. We broke down thinking the worst as we were led into the family room and they told us that it was 'not looking good'."
