DPP regulations to root out criminal elements not enough: secretary-general By Yang Chun-hui, Kuo An-chia and Kayleigh Madjar / Staff reporters, with staff writer Although the Democratic Progressive Party (DPP) has regulations to root out people associated with gangs from the party, in practice there are clearly shortfalls, DPP Secretary-General Lin Hsi-yao (林錫耀) said on Sunday after a party member was implicated in a narcotics and fraud investigation. Chao Chieh-yu (趙介佑) was expelled from the party on Saturday after it was alleged that he was involved in drug trafficking, racketeering, assault and kidnapping related to organized crime. The accusations involve actions Chao allegedly took after joining the DPP in 2014.
