Police General Phao Siyanon (Thai: เผ่า ศรียานนท์, also spelled Sriyanond and Sriyanon; 1 March 1910 – 21 November 1960) was a director general of Thailand's national police who was notorious for his excesses against political opponents. He eventually fled the country and died in exile.

Rise to power

An ambitious army officer of Thai-Burmese ancestry,

Plaek Pibulsonggram

to power.

Made deputy director of the police, Phao quickly staged a show trial of the alleged "assassins" of King Ananda Mahidol (Rama VIII), in which three members of the palace staff were found guilty despite a lack of evidence and were eventually executed even though they had earlier been found innocent.

Police terror

Phao was promoted to the position of director of the police in 1951, by which time he had become one of the country's all-powerful triumvirate. A client of the

CIA, Phao received funds and hardware to build his personal fortune, as well as the expertise of US paramilitaries such as James William Lair to turn the police into an alternative force to oppose his military rival, Sarit Thanarat

.

Phao established an intimate circle of police officers, known generally as the "knights of the diamond ring", which was notorious for its treatment of opponents of the government and the police generals, even resorting to assassination and murder. Their crimes were many:

In March 1949, four
MPs from Isan
and an associate, all one-time disciples of the exiled Pridi, were arrested on charges of treason. They were shot dead by their police escort while supposedly being transferred from one jail to another.

On 12 December 1952,

Kanchanaburi Province

.

A successful newspaper publisher, Ari Liwara, refused to sell out to Phao and was killed in March 1953.

In 1954 Phon Malithong, MP for
Samut Sakhon who provided evidence of corruption against Phao in Parliament, was found tied to a concrete pier in the Chao Phraya River
, having first been strangled.

Phao was extremely wealthy. He demanded protection money from businessmen, rigged the gold exchange, and blackmailed corporations into giving him huge shareholdings. He also profited greatly from the opium trade. Police units transferred opium from the poppy fields of the

CIA

, were instead used to move opium, which the police carefully guarded.
