Three of the men have been sentenced to four years in prison, and the fourth to two years. The court found them guilty of aggravated rape with brutal violence against the victim.
The crime took place in the vicinity of the central railway station in downtown Helsinki during the night of Nov. 1 last year. The victim was a young woman.
According to information obtained by Helsingin Sanomat, three of the men are Iraqi nationals and one is from Syria.
Finnish media reported earlier that at least three of them came to Finland last October as asylum seekers.
In addition to the prison sentences, the count also ordered the offenders to pay a total of 20,000 euros (23,000 U.S. dollars) in compensation to the victim.
All the defendants denied the charges, but the district court considered that the crime of gang rape could be convicted on the basis of sufficient evidence it had collected. Enditem
