A dozen local officials in eastern China have been suspended while authorities investigate the crash of an overloaded school van that killed 11 kindergartners, state media said Wednesday.

A deputy mayor of Guixi, where the crash occurred Monday, and the heads of the city's local education and transportation bureaus are among those suspended, the People's Daily reported.

The principal of the kindergarten, who was driving the speeding van, has been detained after an initial police investigation found he had modified the van to carry more passengers, state broadcaster China Central Television and the official Xinhua news agency.

The privately run school was also found to have been operating without a license and has been ordered closed.
