A Swiss court has ruled that a 27-year-old Afghan man who came to Switzerland as a refugee at the age of two should be deported to Afghanistan after repeatedly committing crimes.

Local media reported that under Swiss law a refugee can be deported even after many years in Switzerland if he is deemed a threat to security or public order.

In this case the young man, who has spent 25 years in Switzerland and does not know his country of origin, appealed to the court after authorities revoked his residency permit in 2015 following a number of convictions for violent behavior.

But last month the court rejected his appeal, Swiss media reported.

The man arrived in Switzerland with his family in 1992 where they were granted asylum.

According to news agencies, the young man was convicted of violent offences three times, which led to a three-year prison sentence in 2010.

A year after being released he again committed an offence and was sentenced to another two years in prison, media reports stated.

Ruling on the man's appeal against his deportation, the court said there was a high risk that he would reoffend, based on the speed of his previous reoffending, his aggressive behavior in prison and the opinion of a psychiatrist, media reports stated.

The defendant said he had no relationship with Afghanistan, that he didn't know the language or the country's customs.

Switzerland’s The Local news portal reported that the current situation in Afghanistan and the fact he was from an ethnic minority also formed part of his argument against his deportation.

However the court drew on the opinion of the Swiss migration office (SEM) which in 2015 said it found no reason to think the man would be treated inhumanely if he returned to Afghanistan, mainly because so much time had passed since the events that led to him and his family fleeing the country as refugees, The Local stated.

The judges however concluded that the public interest in deporting him outweighed his private interest in staying in Switzerland.
