Teoh Beng Hock

MACC officials claimed that the interrogation had lasted for about 9 hours. According to the MACC also, Teoh was freed at 3.45  am—however without proper explanation, his possessions, including his mobile phone, remained in MACC custody. MACC officials also claimed that Teoh asked to stay the night at the MACC office, and was claimed to be last seen alive around 6  am. Teoh was found dead at 1.30  pm later in the day. The investigation had been into allegations that Ean Yong had paid RM2,400 for flags to be used in Merdeka Day celebrations, but not taken delivery of the flags. Teoh's colleagues who had also been questioned claimed that they were put under pressure from MACC officers, including being denied access to legal counsel and food or drink. Teoh's mobile phone was still in the possession of MACC officials when he was found dead at 1.30  pm despite the MACC's claims that Teoh was released at 3.45  am. The mobile phone was later handed to the police for investigation.

On 10 February 2012, Teoh Meng Kee, Beng Hock’s elder brother filed an application at the Court of Appeal to review the open verdict stating that Teoh Beng Hock committed suicide delivered by the Coroner’s Court in 2011, after his application was rejected by the High Court on 1 December 2011. The Court of Appeal on 5 September 2014 set aside the open verdict stating that "a person or persons were responsible" for Teoh's death.

Prime Minister Najib Tun Razak later met with Teoh's family to express his condolences. Najib told them he would direct the Attorney-General and relevant government departments to look into Teoh's family's wish that his child bear the Teoh surname. On 15 August 2009, Soh completed the traditional Chinese marriage ceremonies, together with Teoh Lee Lan, Beng Hock's younger sister, acting as a proxy. Kerk Kim Hock, a distant uncle of Teoh and the family's acting spokesperson, told the press that completion of the marriage rites now entitled Soh to have her name engraved on Teoh's gravestone as his wife.

Teoh Beng Hock (20 April 1979 – 1 July 2009) was a Malaysian journalist and political aide to Ean Yong Hian Wah, a member of the Selangor state legislative assembly and state executive council. On 1 July 2009, the Malaysian Anti-Corruption Commission (MACC) took Teoh into custody for questioning about allegations of corruption. Teoh was found dead the next morning on the rooftop of a building adjacent to the MACC offices. Pakatan Rakyat leaders and a number of federal government officials have called for a Royal Commission of inquiry into Teoh's death.

Teoh was the third child of Teoh Leong Hwee (born 1953). He had an elder brother; Teoh Beng Kee (Chinese: 赵铭基) (born 1976), elder sister; Teoh Lee Jun (Chinese: 赵丽君) and a younger sister; Teoh Lee Lan (1980,Chinese: 赵丽兰). His father was a taxi driver, and his mother, Teng Shuw Hor (1953) is a housewife.

Some lawyers have argued that the law does not authorise the MACC to hold witnesses in custody, and that since Teoh was not a suspect, he should not have been held in custody. The Malaysian Human Rights Commission (SUHAKAM) called the duration of Teoh's questioning "inhumane and cruel." The president of the Bar Council, K. Ragunath, said the MACC had contravened the Federal Constitution by denying Teoh legal counsel during questioning, as well as the Lockup Rules 1953, which require all detainees to be locked up between 6.30  pm and 6.30  am to rest. Ragunath called Teoh's interrogation tantamount to torture. Ean Yong's lawyer insisted that as "Teoh's movement was restricted, this amounts to an arrest," despite the MACC's insistence that Teoh was only a voluntary witness. Mohamad Ramli Manan, a senior official who retired from the Anti-Corruption Agency (before it became the MACC), agreed:
