The legal fight between the city of Munich and the 22-year-old man was decided on by the Bavarian Administrative Court on Friday, which ruled he can be expelled from Germany.

The man could be expected to continue to commit crimes, the judge ruled. And although his deportation is a massive encroachment on his ‘personal, economic and social relationships’, it can be undertaken in the German public interest.

The man first came to the attention of the authorities when he was just 11, after missing school and then beating up his classmates. In April 2005 he was first jailed on two counts of grievous bodily harm and a sexual offence. Further convictions followed, of violence, making threats, theft and possession of drugs.

He was sentenced to two years and nine months in prison, where he seemed to flourish, completing his school certificate and starting a carpentry course. But when he was released in February 2007, he again went off the rails, the court heard, failing to meet his probation officer, and taking drugs. In July 2008 he was again convicted of causing grievous bodily harm and has been in prison since this April.

The court decided that the man could be deported to Turkey, with the judge noting that he spoke broken Turkish and saying he was not ‘integrated’ into German society.
