Klong Prem Central Prison

Klong Prem Central prison (เรือนจํากลางคลองเปรม; ) is a maximum security prison in Chatuchak District, Bangkok, Thailand. The prison has several separate sections. The compound houses up to 20,000 inmates. Within the perimeter of the compound are the Women's Central Prison, often referred to as "Lat Yao" or "Lat Yao women's prison". There is the Central Correction Institution for Drug Addicts (also known as "Bambat Phiset"), Bangkok Special Prison (เรือนจําพิเศษกรุงเทพมหานคร), and the Central Correctional Hospital. The Lat Yao men's section takes custody of male offenders whose sentence term is not over 25 years. As of 2002 the men's section held 1,158 foreigners from 56 countries out of a total of 7,218 prisoners. It is a part of the Thai Department of Corrections.

The Klong Prem section for women houses female death row inmates.

History
Klong Prem Central prison was originally a temporary prison established in 1944 in the Lat Yao District as a consequence of demands during World War II when Thailand was at war with Britain and the United States. In 1959 it was used as a vocational training centre for those who, in the words of the Thai corrections department, "act and behave as gangsters".

In 1960 the old Klong Prem prison on Maha Chai Road (now the Bangkok Corrections Museum) had become overcrowded so all prisoners were transferred to the vocational training centre site. The Interior Ministry established a temporary prison within the new compound by dividing one part into a vocational training centre and the other part into the Lat Yao temporary central prison. In 1972 the Interior Ministry issued orders establishing the prison on Maha Chai Road as the "Bangkok Remand Prison" and the prison in the Lat Yao Subdistrict was designated the "Klong Prem Central Prison".

Visiting Klong Prem
Klong Prem Central Prison allows the families and pre-registered guests of inmates to visit prisoners. Visiting rules and times vary and international visitors have some special privileges. Different days are allocated to certain cell blocks. Weekend visits are typically prohibited. Additional privileges (e.g., phones, longer visits) when visiting foreign prisoners can sometimes be attained with a letter from the appropriate embassy or with bribes to prison guards. Food for prisoners can be purchased at the commissary by completing a form listing the items to be purchased and the prisoner's name. After paying for the items, the order is generally delivered that evening or the next day.

As of October 2018, prisoners are normally held in Bangkok Remand Prison until sentencing. After sentencing, they may be sent to either the main prison, Bambat Phiset (for drugs offences), or complete their sentence in Bangkok Remand Prison. In Bangkok Remand Prison there are eight buildings in which prisoners may be held.

Prison World Cup
With the large number of foreign nationals at Klong Prem, the prison is able to hold a football World Cup. Teams of 10 are chosen by prison staff to represent Nigeria, Japan, the US, Italy, France, England, Germany, and Thailand. Games consist of two 20-minute halves on a half-sized pitch. The winners are given a replica of the real World Cup trophy, which is made of wood in the prison workshop.

Current and former notable prisoners
Foreign prisoners are concentrated in Building 2, and those prisoners may have contact visits for several days providing visitors can demonstrate they have traveled from another country. As of June 2010, there are many foreign prisoners in other buildings of the prison complex.
