Malaysia's government has been urged to reinvestigate the disappearances of a Christian pastor and a Muslim activist after a public inquiry concluded the duo were abducted by the police special branch over matters against Islam.

Amri Che Mat, who ran a Muslim organization, disappeared on Nov. 24, 2016. Pastor Raymond Koh disappeared on Feb. 13, 2017, while being investigated for proselytization of Muslims.

The National Human Rights Commission on Wednesday concluded after a two-year investigation that the men were victims of "enforced disappearance" involving the special branch. It said the men had been targeted and abducted in similar fashion by men in black.

Rights groups, lawmakers and a Christian body said Thursday a new investigation should be done to find the truth and punish the perpetrators.
