Taipei mayor Chiang Wan-an's administration is facing a corruption probe, bad news for a city government that has leaned on a clean-hands image.

• Lin Yu-yi, head of Taipei's Feitsui Reservoir Administration, is suspected of improperly using public money while in office.
• Anti-corruption investigators opened the case after a tip-off and searched two locations under prosecutors' direction.
• Lin and four staff handling the accounts were called in for questioning; documents were seized and the probe continues.
• Lin is a 30-year public servant hired by Chiang in December 2022, giving the scandal a direct line to the mayor's office.

Outlook: Prosecutors will keep digging through the seized records, and the political damage to Chiang's city government will depend on whether charges follow.
