Chalor Kerdthes

The Blue Diamond Affair is a series of unsolved crimes and embittered diplomatic relations triggered by the 1989 theft of gems belonging to the House of Saud by a Thai employee. The affair has soured relations between Saudi Arabia and Thailand for more than 20 years.

In 1989, Kriangkrai Techamong, a Thai worker, stole jewellery and other valuable gems from the palace of Prince Faisal bin Fahd, where he was employed as a janitor. Kriangkrai had access to the prince's bedroom and hid the stolen jewellery in a vacuum cleaner bag at the palace. It included a valuable blue diamond and other gems, which Kriangkrai then managed to ship to his home in Lampang Province, Thailand.

A Royal Thai Police investigation by a team headed by Lieutenant-General Chalor Kerdthes led to Kriangkrai's arrest and the recovery of most of the stolen jewellery. Kriangkai was sentenced to seven years in prison, but he was released after three years as he cooperated with the police and had confessed.

Lieutenant-General Chalor's team flew to Saudi Arabia to return the stolen items. However, the Saudi Arabian authorities discovered that the blue diamond was missing and that about half of the gems returned were fake.

Mohammad al-Ruwaili, a Saudi Arabian businessman close to the Saudi royal family, travelled to Bangkok to investigate on his own. He went missing on 12 February 1990 and is presumed to have been murdered. Several days prior to his disappearance, three officials from the Saudi Embassy had been shot dead in Bangkok. The murders remain unsolved, and no connection to the jewelry theft has been established, despite the Saudi government's view "...that the Thai government had not done enough to resolve the mystery surrounding Al-Ruwaili's assassination and that of three other Saudi diplomats."

Lieutenant-General Chalor was later charged and convicted of ordering the 1995 murder of the wife and son of a gem dealer allegedly involved in the affair, and he was sentenced to death. The Thai Supreme Court upheld the judgement and sentenced Chalor to death on 16 October 2009. Six other policemen were also convicted of involvement in the murders. However, Chalor's sentence was reduced to fifty years imprisonment by King Bhumibol Adulyadej on the King's 84th birthday.
