A Communist Party official in charge of the Chinese capital, Beijing, has become the latest prominent political figure ensnared in a spreading anti-corruption crackdown.

The ruling party's anti-graft agency said Wednesday it is investigating Lu Xiwen, deputy secretary of the capital's party committee. It said she is suspected of "severe disciplinary violations" — the party's term for corruption.

Thousands of officials of state-owned companies have been investigated during the 3-year-old campaign led by President Xi Jinping.

Also this week, the anti-graft agency said it was investigating a deputy mayor of Shanghai.
