According to the prosecution, the man, 28, along with others, assaulted a captive, and the police got access to a film that shows the man taking part in the abuse. The man is in custody.
In September of 2013, the man received permanent residency in Sweden and that is why he is being prosecuted here.
Prosecutor Hanna Lemoine told news agency TT that she believes this is the first time that someone in Sweden is being prosecuted for a crime committed in the Syrian civil war.
In the summer of 2012, the man in question participated in the civil war, on the opposition side, with the Free Syrian Army. The victim of the crime is said to have been a supporter of the Assad regime.
