Two people have been killed and several others have been injured in a shooting incident in Finland.
An 18-year-old man wearing camouflage clothing was arrested after the shooting in Hyvinkaa, a small town 56km north of the capital Helsinki.
The motive for the shooting remains unclear.
It followed a series of shooting sprees in Finland in recent years and came less than a year after anti-immigrant gunman Anders Behring Breivik killed 77 people in a rampage in neighbouring Norway.
The suspect had no criminal background and police said he likely acted alone.
Police could not comment on whether the gunman knew his victims.
The victims were a man and a woman, aged 18.
Seven others were wounded, including a policewoman who is in a critical condition.
Regional police chief inspector Timo Leppala said the shootings were first reported before 2am local time.
The suspect fled but was detained a few hours later. Police said they found two rifles afterwards.
Finland has one of the highest gun ownership rates in the world and a series of mass shootings prompted the government to toughen its gun laws last June.
The suspect in this latest case did not have a licence, according to police.
