Kuala Lumpur police have confirmed that Datuk Seri Thomas Hah Tiing Siu, husband of missing Datin Seri Pamela Ling Yueh, is under investigation in connection with her disappearance.

When asked if Hah is considered a suspect, Kuala Lumpur police chief Commissioner Datuk Rusdi Mohd Isa said only: “Under investigation.” He added that, as of today, statements from 27 witnesses have been recorded.
Police intend to take statements from Ling’s three children and other potential witnesses in Singapore, with assistance from Interpol. Putrajaya district police chief Assistant Commissioner Aidi Sham Mohamed confirmed arrangements are being made for the interviews to be conducted at the Malaysian Embassy in Singapore.
Inspector-General of Police Tan Sri Razarudin Husain previously stated that authorities were examining the possibility of Hah’s involvement in Ling’s disappearance. Both Ling and Hah have been under investigation by the Malaysian Anti-Corruption Commission (MACC) since May 2024 for alleged corruption and money laundering.
Ling went missing on 9 April while en route to the MACC headquarters to assist in a money laundering probe. Her e-hailing ride was reportedly intercepted by unidentified individuals in multiple vehicles. Her lawyer lodged a police report the same day after she failed to appear.
To date, there has been no ransom demand. Police are also exploring the possibility that Ling may have fled abroad. However, Aidi Sham noted that her movements were restricted by MACC at the time due to the ongoing investigation.
Ling’s family lawyer, Sangeet Kaur Deo, has raised serious concerns over MACC’s handling of the case. She claimed MACC failed to disclose critical details in its version of events and had served notices improperly through Ling’s father. She also accused the agency of using a previously settled arrest warrant to lure Ling from Singapore to Kuala Lumpur.
Sangeet revealed that Ling had initiated matrimonial proceedings in Singapore involving assets worth millions across various jurisdictions. Hah had filed a countersuit in Malaysia, prompting Ling to initiate legal action in Singapore’s High Court, alleging fraud and forgery.
She criticised what she described as “aggressive MACC interference” in a private dispute, calling it a misuse of public power. Sangeet also questioned the legality of the unexplained travel ban imposed on Ling and MACC’s refusal to clarify whether she was a suspect or simply assisting with investigations.
“An immediate, independent and transparent investigation into the MACC’s role is essential,” she said. “The authorities must not assume that this will be just another national scandal quietly swept under the carpet.”
Previously, MACC stated that an investigation paper was opened on 28 May last year and an arrest warrant was issued in December after Ling allegedly failed to cooperate.
