Taiwanese prosecutors are widening a corruption case against KMT lawmaker Chen Hsueh-sheng, bad news for him and his office staff, and another blow to the party's image.

• Taipei prosecutors ran a fresh round of searches at four locations and called in five people, including Chen's younger brother, who runs his office.
• Chen is accused of pocketing salaries meant for legislative aides by putting relatives and friends on the payroll.
• He is also suspected of leaning on state oil firm CPC to cancel a contract with a shipping company, saving that firm the cost of arranging replacement transport.
• An earlier sweep in August hit 35 locations, including his home, his legislative office and several shipping firms, and pulled in 27 people.
• Chen was released on bail and barred from leaving Taiwan by land or sea while the investigation continues.

Outlook: Prosecutors are still questioning witnesses over whether aide money was funneled back to the office, and formal charges look likely if the money trail holds up.
