BANGKOK, May 8 (Reuters) - Japanese carmaker Toyota Motor Corp (7203.T) has stopped sales and deliveries of its Yaris Ativ in Thailand, senior officials said on Monday, after its affiliate Daihatsu rigged part of the door in side-collision safety tests. Toyota was working with the Thai government to resume sales of the model, which has been produced in Toyota's Gateway plant in Chachoengsao province, and further investigation was underway. "If development had been carried out under appropriate conditions, this kind of problem would of course not have happened," Maeda said. Daihatsu has said that some 76,000 of those vehicles were Yaris Ativs mainly bound for Thailand, Mexico and the Gulf Cooperation Council. Toyota President Koji Sato, who took over the top job from Toyoda on April 1, was not at the press conference.
