A senior Taiwanese opposition lawmaker is now a corruption suspect, a damaging blow to the KMT and to public trust in how legislators spend public money.

• Prosecutors in Taipei raided KMT legislator Chen Hsueh-sheng's home, his Legislative Yuan office and his Matsu service center, then took him in for overnight questioning.
• He is accused of listing relatives as fake staff to collect government aide salaries, and of letting a shipping company pay the wages of one of his real assistants.
• Investigators also suspect he leaned on state-run oil firm CPC to cancel a contract early, letting that shipping company off the hook for the rest of the deal.
• The sweep hit 35 locations across Taipei, Matsu and Kinmen and pulled in 27 people, including his brother and firms tied to a former Kinmen county chief's family.

Outlook: Prosecutors are still gathering evidence and are building the case around Taiwan's anti-corruption law, so formal charges or detention requests could follow within days.
