Helsinki police think they have identified the minor who perpetrated the fatal stabbing that killed a 24-year-old man on Monday evening at the central train station in the Finnish capital.
The suspect is a 16-year-old boy, who was taken into police custody on Tuesday.
The fatal assault occurred after a brawl between three men and a group of seven minors of foreign origin in the tunnel entrance to tracks 1 and 2.
In the initial phase of the investigation, the police suspected that the seven minors were involved in the murder. However, as the investigations progressed, all signs pointed to a prime suspect, who now remains under arrest.
The other six minors who were part of the group were caught on Monday soon after the crime was perpetrated in the Malmi station, where they had fled.
All six have been released after being heard by the police.
