Turkish authorities on Sunday arrested a pro-Kurdish opposition MP who had refused to leave parliament for several days after his seat was revoked, his party said. "Our deputy (Omer) Faruk Gergerlioglu has been placed in custody," the Peoples' Democratic Party (HDP), parliament's third largest, said on Twitter. The parliament on Wednesday revoked the seat of Gergerlioglu, an outspoken rights defender, and his accompanying immunity from prosecution after a controversial conviction over a social media post. gkg/jhd/wdb/gle
