A former Taipei water agency head is out on bail over suspected misuse of public money, and the case has become an opening for the opposition ahead of the city's mayoral race.

• Lin Yu-yi, ex-chief of Taipei's Feitsui Reservoir Administration, was released on bail after prosecutors searched his office and questioned him over allegedly taking public funds.
• He is barred from leaving Taiwan by land or sea while the probe continues.
• Puma Shen, the DPP's candidate for Taipei mayor, said the city government's hiring culture needs a hard look and that regular reviews should catch problems earlier.
• Shen also hit the city over flooding after heavy rain, saying its promised AI disaster warnings never reached residents.
• He flagged a rise in fake political accounts on social media ahead of the year-end elections, without saying who is behind them.

Outlook: The investigation will keep running as Taipei's mayoral campaign heats up, and city management is shaping up as a central line of attack.
