TAIPEI (Taiwan News) — An arrest warrant for Thai MP Chaiyamparwaan Manpianjit was withdrawn on Tuesday after the lawmaker surrendered to police voluntarily and denied he raped a Taiwanese tourist.

The Taiwanese tourist alleged Chaiyamparwaan raped her in January, and police said on Feb. 7 they had sought parliamentary approval to arrest the MP. On Tuesday, Thailand’s The Nation reported that Chaiyamparwaan had turned himself in to Chiang Mai police.

Thailand parliamentary rules state that MPs cannot be arrested or summoned for a criminal investigation without the parliament’s approval. However, they can voluntarily submit to the police.

Chiang Mai Deputy Provincial Police Commander Damnoen Kanaong said the MP denied all charges against him during questioning. He also denied reports police asked Chaiyamparwaan for a bribe to drop the case and said he did not know where this claim came from.

Chaiyamparwaan reportedly consented to a DNA test during questioning. According to the Bangkok Post, his representative told Thailand’s House of Representatives that he would comply with a judicial investigation.

Thailand’s House Speaker Wanmuhamadnoor Matha said a parliamentary committee would consider a request for an ethical investigation into Chaiyamparwaan. The most severe result of an ethical investigation is for an MP’s case to be referred to Thailand’s anti-corruption agency, which can imprison or fine those found guilty of misconduct.

Chaiyamparwaan was expelled from Thailand’s main opposition Move Forward Party last year over sexual misconduct allegations. He represents Bangkok as the Thai Progress Party’s only lawmaker.
