Police have arrested a 32-year-old man in connection with the abduction of pastor Raymond Koh, who has been missing since Feb 13.

Selangor police chief Abdul Samah Mat said the suspect was detained in Ampang at 3.30am this morning.

"The suspect had contacted the victim's family member a day before, asking for a sum of money for the release of the pastor," Abdul Samah said in a media statement.

According to Oriental Daily, the man had sought RM30,000 from the family.

Abdul Samah said the suspect has been remanded for four days to facilitate investigations.

"The case is being investigated under Section 365 of the Penal Code for intent to kidnap or abduct and Section 385 of the Penal Code for extortion," he said.

He said police are still investigating the case and appealed to the public to come forward with information.

Abdul Samah also asked members of the public not to speculate on the matter.

Koh was abducted by several masked man in black SUVs after blocking his car in Petaling Jaya.

Following this, there were speculations that the case could be related to religion.

In 2011, the 62-year-old pastor was embroiled in a controversy after his NGO, Harapan Komuniti, was accused by the Selangor Islamic Religious Department (Jais) of proselytising Muslims, following a raid at a thanksgiving and fundraising dinner at the Damansara Utama Methodist Church.
