Borstal
A borstal was a type of youth detention centre in the United Kingdom and the Commonwealth. In India, it is known as a borstal school.
Borstals were run by HM Prison Service and intended to reform seriously delinquent young people. The word is sometimes used loosely to apply to other kinds of youth institution or reformatory, such as Approved Schools and Detention Centres. The court sentence was officially called "borstal training". Borstals were originally for offenders under 21, but in the 1930s the age was increased to under 23. The Criminal Justice Act 1982 abolished the borstal system in the UK, introducing youth custody centres instead.
