A DAP lawmaker has urged the police to not keep family members of pastor Raymond Koh in the dark on the ongoing investigations into his abduction.

Bukit Mertajam MP Steven Sim said in a statement today it has been 18 days since Koh was first reported missing but his friends and family are still waiting for information from the police.

Among others, Sim raised questions on progress of the investigations by the special task force announced by inspector-general of police Khalid Abu Bakar.

"Koh's son Jonathan lodged a second police report two days ago because of the lack of news after more than two weeks.

"While they may have tactical reasons to maintain confidentiality, I urge the police to at least update the family and not keep Koh’s loved ones in the dark," Sim (photo) said.

The Star on Tuesday quoted Jonathan as saying the second police report was lodged over suspicion that his father has been murdered by the abductor.

Sim also echoed concerns that Koh’s abduction was not an ordinary crime but instead linked to possible act of terror.

"The well-executed operation by the kidnappers, who did it in broad daylight, sends a chill to the Malaysian public.

"If this can happen to a harmless and charitable person such as Pastor Koh, it can happen to anyone," he said in urging police to deploy every possible resources to rescue Koh and arrest the perpetrators.

Koh, 62, was reportedly abducted on Feb 13, by a group of masked men less than 100 metres from the Police Housing Complex in Kelana Jaya.

The pastor had made headlines in 2011 after his NGO, Harapan Komunitas, was accused by the Selangor Islamic Religious Department of proselytising Muslims during a dinner at a church in Kota Damansara.
