A wanted member of the overseas group “Hong Kong Parliament” has been arrested in Thailand for overstaying her visa and is reportedly set to be deported to mainland China.

The organisation said on Friday that Zhang Xinyan, who took part in what it called a parliamentary election and was sworn in as a member last year, was recently arrested in Thailand for overstaying her visa.

It was not immediately clear what type of visa Zhang held.

In a reply to the South China Morning Post on Saturday, a Hong Kong government spokesman declined to comment on media reports about law enforcement actions in other jurisdictions.

But he stressed that authorities would spare no effort in pursuing national security fugitives.

The activist organisation claimed that Zhang held refugee status granted by the Office of the United Nations High Commissioner for Refugees (UNHCR), adding that she had been told she would be deported to the mainland.
